AT&T Mobility FAQ – Wikibooks, open books for an open world

Solutions to Frequently Asked Questions concerning AT&T Mobility (also referred to as Wi-fi from AT&T, previously Cingular Wi-fi). Based by John Navas.

Common Data[edit]

What’s a SIM?[edit]

See Subscriber Id Module

Do GSM Telephones Should be Activated?[edit]

No. Solely the SIM must be activated, and a GSM cellphone will work so long as:

  • An lively SIM is put in within the cellphone. (A SIM will be moved from cellphone to cellphone by the consumer.)
  • The cellphone is not “locked” to another service. (See What’s locking?)
  • The cellphone helps the proper band(s) for the community (850 and 1900 within the case of AT&T).

What’s Locking?[edit]

See Subsidy lock (mobile).

When am I Eligible for a Cellphone Improve?[edit]

See Improve Your Cellphone
Notice: “TDMA” (Digital AMPS) prospects might solely improve by switching to GSM, which entails a brand new fee plan that will not be nearly as good because the previous fee plan.

Pay Your Invoice: *PAY (*729)

Rollover[edit]

What’s Rollover?[edit]

Rollover is a promotional device which works beneath the promoting slogan, “They’re your minutes, maintain’em”. On the finish of every billing cycle, all unused anytime(daytime) minutes roll over to your subsequent billing cycle. For instance, in case you are on the Nation 450 plan and you employ 300 of your 450 anytime minutes, then at the beginning of the following billing cycle you’ll have 450 anytime minutes, and 150 rollover minutes, totaling at 600 usable anytime minutes. Rollover is barely out there on plans which are $39.99 and up.

How does Rollover Expire?[edit]

    • A GSM cellphone will solely work within the frequency bands it helps—be sure you examine. 850 and 1900 bands are principally confined to the USA and Canada; most different international locations use 900 and 1800 bands.
    • Roaming expenses apply when utilizing a AT&T SIM outdoors of AT&T Nationwide protection.
    • See Worldwide Calling for cellphone use outdoors of AT&T Nationwide protection.

Tower Areas[edit]

Cell Cellphone Reception and Tower Search

Why does one cellphone get higher sign than one other?[edit]

Whereas there are variations in capability to deal with weak sign circumstances between completely different telephones, such variations are often modest absent a defect in one of many telephones. Substantial efficiency variations in a given location are thus more likely to be resulting from completely different community programming of the SIMs than to variations within the telephones.
For instance, one cellphone may need a SIM “homed” on the previous ATTWS (blue) community and the opposite cellphone may need a SIM homed on the previous Cingular (orange) community. If each blue and orange indicators are current in a given location, and if (say) the blue sign is nice whereas the orange sign is poor, then the cellphone homed on blue may effectively exhibit higher efficiency than the cellphone homed on orange. It is because a GSM cellphone will at all times want its residence community to a non-home community even when the non-home community has a a lot better sign — it should solely roam on the non-home community if there is not a “usable” residence community sign.
Such a distinction may even occur when each telephones have orange SIMs as a result of ENS (64Okay) SIMs will be homed by AT&T OTA (over the air) to both the orange community or the blue community. (See Does ENS make for higher protection and/or connections?) Thus to meaningfully evaluate two telephones in a given location, the identical SIM needs to be used to check every cellphone.
One other attainable reason for efficiency variations is band assist. AT&T makes use of each the 850 band and the 1900 band (relying on location), so a cellphone with assist for each 850 and 1900 bands might effectively carry out higher in a given location than a cellphone with assist for less than the 1900 band.

What is the Distinction Between 800 and 850 bands?[edit]

There may be no distinction between 800 and 850 bands — they’re the identical frequencies between 800 and 900 Mhz. Because the time period 800 had change into related to “TDMA”, 850 was coined to differentiate GSM.

What Can I Do About Poor Protection in My Space?[edit]

  • Name Buyer Care (611) and ask to be transferred to Tech Help.
  • Click on on http://assist.cingular.com/, enter, after which click on on report community situation within the contact us part. (Though the positioning is barely “meant for former AT&T Wi-fi prospects”, different Cingular prospects can use the positioning by going by way of a 2nd login display screen.)

Is the 800/850 Band Higher Than 1900?[edit]

You’ll have heard that 800 or 850 band is “higher” than the 1900 band as a result of:

  • It travels farther. That is not true. What’s true is that there is usually a distinction in vary resulting from energy:
  • Most energy within the 800 band is Three watts.
  • Most energy within the 1900 band is 2 watts.
It will not be intuitively apparent, however that is solely about 18% much less vary for 1900, or a most of about 20% extra towers alongside a flat rural freeway strip, or a most of 50% extra towers in space protection, after which solely when vary is restricted solely by most energy, which is never the case in metro areas. Tower spacing is often solely close to most in flat rural areas (and present small handsets do not come near most energy ranges).
  • It penetrates buildings higher. It isn’t that straightforward: Whereas 1900 penetrates partitions much less effectively than 800/850, it does a greater job of penetrating small openings (e.g., home windows). Basically the penetration distinction tends to be comparatively small.
For an in depth technical evaluation, see CS 294-7: Radio Propagation [Randy H. Katz, CS Division, University of California, Berkeley]

How Can I Enhance My Sign High quality?[edit]

  • Change of House Community
    A GSM cell machine (e.g., cellphone) is “homed” to a specific community, and can solely roam on a special community when there isn’t any “usable” community sign, even when the roaming community sign is a lot better than the house community sign. Till AT&T completes the mixing of the previous Cingular (orange) community and the previous AT&T Wi-fi Service (blue) community (anticipated in mid-to-late 2006), a given cell machine shall be homed on one community or the opposite, and can thus want that community over the opposite community even when the opposite community has a greater sign. In such circumstances, and given an ENS-capable cell machine and (64Okay orange) SIM, it might be attainable to enhance sign high quality by:
  • Name AT&T Buyer Care (611).
  • Ask to be transferred to Technical Help as a result of you may have poor sign high quality.
  • Ask Technical Help to modify your property community (orange to blue, or blue to orange).
Notes:

  • ENS will not work with AT&T Wi-fi Service (blue) cell gadgets (or SIMs).
  • Even with ENS, a cell machine nonetheless is not in a position to mechanically choose the higher community sign — GSM roaming guidelines nonetheless apply.
  • AT&T began promoting ENS-capable gadgets in late 2004.
  • It might take as much as 24 hours for a house community swap to happen.
  • It might assist to show the cellphone off and again on.
  • Whereas a swap in residence community might enhance sign high quality in a single space, it might degrade sign high quality in a special space.
  • Higher Cellphone
    Telephones differ in how effectively they carry out with weaker indicators (as in different issues), and thus a special (higher) cellphone may assist in poor sign areas. Basically, costlier telephones are inclined to have higher sign dealing with than inexpensive telephones. Of the assorted manufacturers, Nokia gadgets are usually well-regarded, though different main manufacturers (e.g., Sony Ericsson, Motorola) even have higher gadgets.
    Exterior Antenna
    The small antenna in most cell gadgets compromises efficiency for smaller dimension, and significantly-to-substantially higher efficiency is mostly attainable with an exterior antenna (related to the cell machine with a particular cable). Exterior antenna choices embrace:
  • Energetic Repeater
    The place there’s a usable out of doors sign, an lively repeater might present improved indoor sign. An lively repeater consists of (1) an outside antenna, related by cable to (2) a two-way sign amplifier (often situated indoors), related by cable to (3) an indoor antenna. Care have to be taken to make sure that: (a) the system is correctly designed for the proper know-how (GSM) and bands (850 and/or 1900); (b) the indoor sign is sufficiently remoted from the out of doors sign; and (c) no interference in any other case outcomes. The benefits over exterior antennas aren’t any antenna connections wanted to cell gadgets and probably better efficiency; the disadvantages are complexity and price of not less than a number of hundred {dollars}. Sources embrace:
    Sign Boosters
    Stick-on “sign boosters” change the antenna efficiency of the cellphone in random methods relying on the mannequin of cellphone and the place precisely you stick it. Dozens of RF engineers on the cellphone producer spend their careers optimizing antenna efficiency, so the change will usually be for the more serious. Since RF optimization includes lots of of advanced tradeoffs, it’s attainable {that a} stick-on booster will enhance reception in a single or two circumstances, whereas degrading it in lots of extra circumstances. General, sign boosters usually make your sign worse.

What are messages from 36245?[edit]

36245 (which spells “e mail” on a cellphone keypad) is the variety of the AT&T Mobility GSM-standard email-to-SMS gateway. When e mail is addressed to NUMBER@Cell.MyCingular.com, the gateway forwards to that NUMBER as SMS message(s). The sender’s e mail handle is the primary merchandise within the message, adopted by the topic (if any) in parentheses. To Reply to the sender, you’ll have to alter the message addressing (relying in your cellphone). Use of the AT&T MEdia email-to-SMS gateway is most popular — see What are messages from numbers like 1010100004?.
If the email-to-MMS gateway is used as an alternative of the email-to-SMS gateway (by addressing e mail to NUMBER@mms.att.internet), addressing (together with replies from a cellphone) shall be cleaner, and messages will be for much longer, however MMS messages are costlier than SMS messages.

What are messages from numbers like 1010100004?[edit]

It is a particular gateway quantity generated by the AT&T MEdia email-to-SMS gateway. When e mail is addressed to NUMBER@CingularME.com or MEdia_ID@CingularME.com, the incoming gateway forwards to that NUMBER (or the NUMBER for that MEdia_ID) as SMS message(s), and that particular gateway quantity is used to trace the e-mail handle of the sender. Reply to the sender is straightforward, as a result of the cellphone will mechanically reply to that particular gateway quantity, which can trigger the outgoing AT&T gateway to ahead to the e-mail handle of the unique sender. That is thus the most popular methodology of AT&T email-to-SMS messaging.

Information Service[edit]

Can I take advantage of my Cellphone as a Modem?[edit]

Most GSM telephones can be utilized as “dial-up” (CSD) modems, and lots of may also be used as GPRS (packet information) modems. For this to work, your cellphone have to be “tethered” (related) to your pc by:

What’s the Distinction Between CSD, GPRS/EGPRS(EDGE) and HSDPA?[edit]

CSD
Makes a devoted information connection like a standard wired modem. Velocity (on AT&T) restricted to 9600 bps. Charged like voice minutes (and isn’t Cell to Cell). Should be enabled by AT&T to work (which can require a $4/month information characteristic), and is barely out there to “orange” accounts (Cingular, not AT&T Wi-fi) and on the “orange” community.
  • A GSM cellphone has no actual dialup modem, only a type of digital modem which makes a connection to a service’s IWU (Inter Working Unit), situated in some service middle. The IWU has the precise modem that may make analog information calls over the PSTN (public switched phone community). If the service does not present an IWU, or in case your account is not provisioned for CSD (Circuit Switched Information), then a GSM cellphone can not make information and/or fax calls. In case your account is provisioned for CSD, then all you want is to put in the cellphone as a modem with Home windows Dial-Up Networking.
GPRS/EGPRS(EDGE)
Makes a packet information connection, sharing channel(s) with packets to/from different customers, connecting and disconnecting on demand. A lot sooner and extra environment friendly than CSD. Charged by the quantity of knowledge transferred, as (costly) Pay-As-You-Go if you do not have a information package deal (MEdia or Information Join).
HSDPA
See What’s BroadbandConnect?
See additionally What information speeds are attainable with AT&T (GSM)?

What’s the distinction between MEdia and Information Join?[edit]

MEdia
Supposed to be used solely on a cellular phone. “Tethering” works, however is discouraged, and AT&T reserves the correct to deny service based mostly on utilization. (See MEdia Authorized Notices) Makes use of a WAP profile, however entry to your entire Web is offered. VPN might not work. No Information Acceleration.
Information Join
Supposed to be used with PDA or pc, relying on particular package deal. Makes use of an Web profile. VPN is supported. Information Acceleration is non-compulsory.

What’s Information Acceleration?[edit]

Information Acceleration, an non-compulsory characteristic out there solely on CSD and Information Join (not MEdia Internet) service, speeds Web entry primarily by compressing pictures. The tradeoff is decrease picture high quality. See Wi-fi Information Throughput Orange Paper (Adobe PDF format). Information Acceleration is well managed should you use AT&T Communication Supervisor. If as an alternative configuring manually, Information Acceleration is enabled or disabled with “DA” in login Userid as follows:

What information speeds are attainable with AT&T (GSM)?[edit]

CSD
Velocity of 9.6 Kbps (9600 bps, or about 1K Bytes/sec). Out there in most GSM areas, however being phased out.
GPRS
With a Class 10 machine and good sign, typical obtain speeds of about 50 Kbps (about 6K Bytes/sec). Out there in all GSM areas.
EGPRS(EDGE)
With a Class 10 machine and good sign, typical obtain speeds of about 150 Kbps (about 18.5K Bytes/sec). Latency (as measured by ping) of about 300 ms. Broadly out there. Backward appropriate to GPRS.
UMTS
Typical obtain speeds of 200-320 Kbps (or about 2x EGPRS). Out there in 6 markets as of 4Q 2005. Most (however not all; e.g., Novatel U520) gadgets are backward appropriate to EGPRS and GPRS.
HSDPA (BroadbandConnect)
Typical speeds are anticipated to be 400-700 Kbps (or about 4x EGPRS). Latency (as measured by ping) anticipated to be about 150 ms (or about half of EGPRS). Launched in 16 markets in December 2005. Backward appropriate to UMTS, EGPRS and GPRS.

Why is my GPRS, EDGE, UMTS, or HSDPA so gradual?[edit]

Poor Sign
Good sign (usually not less than Three bars) is required for greatest efficiency.
Cell System Capabilities
Handsets (and PC Playing cards) don’t all have the identical information efficiency, which is decided partly by GPRS/EGPRS(EDGE) Multislot Class. Basically, as of this writing, all moderately present GPRS/EGRPS(EDGE)-capable gadgets from Ericsson and Sony Ericsson assist Class 8 (4+1) and Class 10 (4+2, max of 5), whereas most Nokia gadgets are restricted to slower Class 2 (2+1), Class 4 (3+1), and Class 6 (3+2, max 4). Motorola has each Class Four and Class Eight gadgets. (The primary quantity is the max downlink slots, and the quantity after the “+” is the max uplink slots.) This may translate into a considerable distinction in throughput if supported by the service:

Class 4 & 6
50% sooner on downlink than Class 2.
Class 8 & 10
100% sooner on downlink than Class 2.
33% sooner on downlink than Class 4 & 6.
Class 10
100% sooner on uplink than Class 2, 4 & 8.
Serial Port Bottleneck
Connections between handsets and “tethered” gadgets (e.g., pocket book pc, PDA) are usually applied as a serial port, both actual or digital, and port velocity often defaults to 115 Kbps. (A Bluetooth stack applied as a digital serial port might go as quick as 921 Kbps, however will run at solely 115 Kbps by default.) Whereas 115 Kbps is mostly quick sufficient for GPRS, it may be a bottleneck for EGPRS(EDGE) and UMTS/HSDPA. Advisable minimal port speeds:

  • GPRS: 230 Kbps
  • EGPRS(EDGE): 460 Kbps
  • UMTS/HSDPA: 920 Kbps
