AT&T Prepaid (formerly GoPhone)Edit

AT&T is the biggest GSM-based provider in the US, rivaling only with Verizon. It has the biggest coverage nationwide aside from Verizon and gives the best compatibility with devices both within and from outside the United States.

AT&T's 2G was shut down by January 1st, 2017 and is no longer available. 3G is on 850 MHz and 1900 MHz up to HSPA+. 4G/LTE is on 700 MHz (B12/17, B14, B29), 850 MHz (B5), 1700 MHz (B4, B66), 1900 MHz (B2) and 2300 MHz (B30) (see Basics chapter for details).

Availability and start-upEdit

Their prepaid lines now are all called AT&T Prepaid. A starter pack is called “AT&T Prepaid SIM card kit”. The SIM card only is referred as “Bring your own” (device). The SIM card is available for up to $20 from AT&T stores (locator) or for $9.99 online to be sent to an US postal address or at other stores such as Best Buy, Target and Walmart (also for $9.99). Mini-, micro- and nano-SIMs are available. Take care that some mall kiosks like to charge you more for the SIM card. But some waive the SIM fee if you buy a top up at the same time.

Alternatively, you can buy at online dealers e.g. on eBay to be shipped overseas for a surcharge. Commercial vendors like them here ship it worldwide for a steep surcharge: For instance the $45 plan with SIM is sold at £71 (= $88) which constitutes an almost 100% surcharge.

There are two different kinds of plans on offer: one with voice, texts and data for phones and another with data-only for tablets, routers and modems. The data-only plans work in phones and modems too, but are intended for tablet use and your phone will not send/receive calls or text messages with a data-only SIM (even though it still has a phone number). To avoid confusion in shops, state that you want to use it in a tablet, even if you plan to put the data-only SIM into a phone. There is no need to conceal anymore that you bring an iPhone from overseas. This caused problems until some years ago, but AT&T now welcomes foreign iPhones too.

The SIM cards sold in stores like Target, Best Buy, and Walmart work with both the data-only and phone plans, you decide when activating the SIM which kind of plan to use and you can change from one type to another later. The instructions with the SIM explain how to activate it, which is done differently for the plans.

If you buy the SIM in an AT&T store, then keep your receipt, it shows the phone number of the SIM card. If you activate the SIM yourself, you will receive an SMS message showing your phone number after activation. SIM cards bought in their stores normally don't have any instructions or other information and you get only the plain SIM card.


Activation can be done in three ways:

  • from your GoPhone (phones only): place card in phone, turn it on, select rate plan, type activation code, select ZIP code, send, turn it off and turn it on after 10 minutes to be activated.
  • from any phone: call 877 426 0525 and follow instructions

When you are not in the US and want to activate your SIM before (e.g. to know your number ahead) follow this procedure: Use the online link (see above), as IMEI enter in the form (Any IMEI will work), you can add a non US-based credit card, but choose USA as country and use any US address you can think of. AT&T uses the entered IMEI number to determine, if device is AT&T branded. If the system determines that the IMEI is not an AT&T branded device, select one of the following options from the drop down menu. (Phone,Tablet,Hotspot,Data Device). LTE is enabled on all devices now by default. As ZIP code take any US ZIP code, the ZIP code is needed so the carrier can assign a phone number based on the area code. Then you can recharge, but can’t choose your plan though, because the verification SMS won’t be forwarded roaming abroad. For that you have to call customer service at +1-800-331-0500 to add your data plan manually. Have in mind, that the plan starts from this moment on.

Recharges and validityEdit

At least some credit cards not issued in the US can be added to the account (see above). If you don’t succeed in adding yours, just buy vouchers, called refill cards in the US. They are available at AT&T stores, many supermarkets, gas stations, Walgreen’s and CVS drugstores, 7-Eleven and many other outlets. Minimum value is $15. A refill of $15 is valid for 30 days, up to $50 for 90 days and from $100 for 365 days. Take care: If not used up and extended in time, your credit will be lost, the account closed and the SIM card terminated. The account closure time differs between phone and data-only plans. As of 2015 the phone plans close 60 days after last credit expiry and data plans 365 days after last expiry.

Voice plans with dataEdit

These following monthly packages for 30 days are offered for smartphones:

Price Auto-pay Voice


$30 $25 unlimited

to US

No data included, add-on 250 MB of data for $5
$35 $30 1 GB included in US, beyond throttled to 128 kbps, roll-over
$50 $45 unlimited to USA, MEX, CAN 8 GB included in US/MEX/CAN, then throttled to 128 kbps; roll-over
$65 $55 Unlimited data in US/MEX/CAN (depriorization during network congestion, video streaming max of 1.5 Mbps, no hotspot use)
$85 $75 Unlimited data in US/MEX/CAN (22 GB before subject to depriorization during network congestion) max. 10 GB for data hotspot/tethering (US usage only, throttled to 128 kbps beyond)
All plans include unlimited domestic SMS and MMS and international SMS to more than 100 countries. Upsizes can be made up to three times per month and may roll over to the next month. When data volume is used up, speed will be reduced to 128 Kbps. Data default rate outside the mentioned packages is 1c per 5 KB which amounts to $2 per MB. If you link your plan to a credit card by auto-pay, a discount will be applied.

AT&T considers one month to be 30 days, including the day of activation. Monthly plans expire at 11:59pm Central Standard Time on the 30th day of service. If you link it to auto-pay on your credit card, the plans are discounted by $5, but you need to cancel later.

For more data on the limited plans you can add 1 Gb for $10 or 3 GB for $20 valid for the rest of the running time of the base plan.

Unused data on the $35 and $50 plans rolls over to the next month when the plan renews. However, plan data is used before rollover data and rollover data expires after 30 days. That means that unless your data usage alternates from low one month to high the next you are unlikely to be able to use much of your rollover data. 

Daily plans Edit

$2 per day for unlimited domestic voice and text, charged only on the days used. Outgoing call or SMS, or accepting an incoming call, activates the plan for the day. $8.33 is the minimum monthly cost. A $0.25 to $2.50 per month "911" fee is deducted from your prepaid balance in some states. This daily plan expires at 11:59pm in the time zone, where it was activated.

Default data rate on this plan is 1c per 5 KB (= $2/MB), but AT&T actively blocks this default rate on smartphones to avoid bill shock. However, in case AT&T doesn't accurately detect your device type, use caution to avoid accidentally emptying your balance.

Instead a new $1 per day 100 MB Data Day Pass is now available to users on the $2 Day Plan. The new Data Day Pass for Daily plan users is good, since using data doesn't trigger the $2 daily fee, which is only charged if a call is made or received or a text sent. $1 per day for data-only use is a pretty good deal for short-term international visitors or anyone who needs data only occasionally. Visit this site to activate this data pass, or free call 611 from the device.

This $1/day 100 MB day pass expires 24 hours from the time of purchase. Once you have used at least 90 MB you may purchase another pass manually, it doesn't auto-renew. Purchasing a new pass does not expire the remaining MB from the previous pass. To check remaining data enter *777*3#.

Data-only plansEdit

These monthly packages called Data Connect are for tablets, but work on phones and modems too:

  • 10 GB: $50
  • 15 GB: $70

Unused data will not roll over to the next month. Plans expire in 30 days and can be renewed prior to expiration as long as the account is active. They don’t renew automatically and there is no voice nor text on this line. Accounts can be managed online or by calling 866 707 5550. Accounts for data-only plans are cancelled 365 days after the last plan expires (i.e. if you have a plan for January 2019 and it expires on Feb 1st, 2019 then you can still renew the plan anytime until Feb 1st, 2020. After that time the account is closed and you must get a new SIM card). This expiry time is longer than for phone plans (which expire 60 days after the last plan expires). Overage rate is $10 per GB.

Note that AT&T uses the device IMEI No. given during account setup to determine the type of device being connected to the network. If your device can't be ascertained by AT&T's system IMEI, the system will ask what the device is (Phone,Tablet,Data Hotspot), If you later try to go into AT&T's online account management system and change your plan from one of the above listed plans to another (say $50 to $75 data plan) you can only change to phone plans. In order to change the data plan, you must call AT&T and have it changed manually by a customer service representative.

If your device connects proper to the AT&T network, but can't get data connection (only a few AT&T sites), check the appropriate APN (see below). If you then get a message that you don't have any data credit available, even if you have topped up before, your account may have been switched to phone by default (see above). So call 1-800-331-0500 and talk to a technical support representative to activate your plan as data, not as phone.

Thus your prepaid turns to a contract, billed on a credit card. You have to have a MasterCard, VISA or Discover and at least in the US a good credit rating. Be aware, that you need to cancel auto-pay online, if you leave the country, or they will keep on charging your credit card.

Max. speed used to be throttled to 8 Mbps on LTE and 4 Mbps on 3G on all plans but the $60 plan. As of September 2018, this has changed. The $55 unlimited plan is now the only plan with a speed cap at 3 Mbps, with all other plans streaming at whatever max speed AT&T's network allows. For data beyond the 2 GB and 5 GB plan's quota, speed will be throttled to 128 Kbps. All packages will renew automatically, if there is credit. If not, service will be suspended.

For tethering on the $30-$55 plans, they offer a "mobile hotspot" feature for $10 extra. Their "officially supported phone" list for this feature is very short and includes only several specific Android and Windows models. There are workarounds on the internet for other devices.
