AT&T (Go Phone)Edit

AT&T is the biggest GSM-based provider in the US rivalling only with Verizon. It has the biggest coverage nationwide aside from Verizon and gives the best compatibility.

AT&T's 2G was shut down by January 1st, 2017 and is no longer available. 3G is on 850 and 1900 MHz up to HSPA+ and 4G/LTE on 700 (B17), 1700(B4, AWS), 1900 (B2) and 2300 MHz (B30) (see Basics chapter for details).

Availability and start-upEdit

Their prepaid lines are all called GoPhone. A starter pack is called “GoPhone SIM card kit”. The SIM card only is referred as “Bring your own” (device). The SIM card is available for free from AT&T stores (locator) or for $9.99 online to be sent to an US postal address or at other stores such as 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. 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 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 recieve 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 15 times 1 (“111111111111111”), 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 entered IMEI number to determine, if device supports LTE. If it thinks that this device is not LTE-capable, the network will not allow any LTE connections. E.g.“111111111111111” is considered not LTE capable. It's recommended to enter a LTE-capable IMEI, if you need LTE. If LTE is not activated on your account but your phone supports LTE, better disable LTE on your phone. If you don't, your phone may periodically try to switch to LTE, but fails and for the duration of the attempt you may lose connection altogether. As ZIP code take any US ZIP code and as 4 digits of SSN enter “1234”. 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

The following monthly packages are offered for smartphones:

Rate Voice, SMS Data
$ 30 unlimited to US not included, @ $2 per MB or 250 MB for $5
$ 35 unlimited to US 1 GB included in US, then throttled to 128 kbps
$ 45 unlimited to US, Mex, Cdn 6 GB included in US, Mex, Cdn; roll-over data to next month
$ 65 unlimited to US, Mex, Cdn

Unlimited US data at 3 Mbps download, 'unlimited' data roaming in Mex and Cdn too; FUP: 22 GB with depriorization during network congestion

All plans are discounted by $ 5 per month, if you enable auto-pay. 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. The $30 plan doesn't come with data at all. This is why a data add-on card is needed to be purchased for $5 so users can enjoy 250 MB of data.

A profile for a mobile hotspot necessary for tethering on an iPhone is supplied only for the $60 package. 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.

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 at 11:59pm Central Time (not your local time zone) the next day following the day of purchase or upon using the whole allotment. So by purchasing in the morning of the first day, you can get almost 48 hours of usage on one pass.

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 remaing data enter *777*3#.

Data-only plansEdit

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

Rate Data Volume Upsize
$ 25 2 GB 500 MB for $ 10
$ 50 5 GB 1 GB for $ 10
$ 75 8 GB 2 GB for $ 10

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 2015 and it expires on Feb 1st, 2015 then you can still renew the plan anytime until Feb 1st, 2016. 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).

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 defaults the account to a phone, not a data-only account 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 $25 to $50 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.

FreedomPop Edit


FreedomPop launched as a Sprint MVNO in 2012 and claims to have added over one million US customers since launch. In 2016 they began offering FreedomPop GSM service to their US customers.

Business model Edit

FreedomPop uses a business model called 'Freemium' that provides users with a limited amount of free data and phone service and makes money by selling devices and extra features like voice mail and faster data and by charging overage rates for data, texts and minutes after the free allotment is used up. More than 1/2 of all their US customers buy add-ons for pay that are not so cheap after all.

As a freemium provider FreedomPop needs users to sign up for add-on services. They make it easy to add extra cost plans and services, but quite hard to remove them. When you activate a device, by default you get signed up for multiple offers and add-ons which are advertised as free trials. However they are only free for the first month, if you don't cancel them before the month is up they will automatically renew and you will be charged for subsequent months. It's possible to decline some of the add-ons and trials during the initial sign up, but you have to read the sign up pages carefully to find the link to opt out of each one. To disable extra cost services you don't want: Go to My Account > Services and click the Deactivate link next to the services name. Note, that free customers don't get any customers support whatsoever.

AT&T 4G data plan Edit

In 2016, FreedomPop launched a new US-only mobile broadband service running on the AT&T network that includes 4G/LTE for data. The new FreedomPop LTE GSM service is different from the Global service on T-Mobile. It works on AT&T only, whereas Global GSM, which doesn't offer 4G/LTE data, works in 25 countries including the US, where it uses T-Mobile on 2G/3G in the US.

The free AT&T plan includes 200 MB data in up to 4G/LTE on AT&T's US network without roaming. For voice calls and SMS 200 domestic voice minutes and 500 domestic texts per month are additionally available when using the FreedomPop "Messaging" VoIP and messaging app for iOS and Android. The app offers reasonable call quality when used with a good WiFi or 4G signal. There's a bit of lag but volume and clarity are good. Call quality is degraded, but still usable with a strong 3G signal. But with a weak signal or only 2G data calls break up so badly, that it's impossible to carry on a conversation.

Availability Edit

The FreedomPop AT&T SIM is available for free on their website. You'll need to give a postal address in one of the countries where they operate: USA, UK, Spain and soon in Mexico. A credit card must be linked to the SIM even for using only free services. You'll need to give these information when ordering. Internatl. credit card (Visa, MasterCard) are normally accepted. From November 2017 their products including the SIM card for $5 are available at 1100 Target stores in the US (Target store locator, as they have around 1800 stores, it may not available at all locations). They provide an online account management with detailed call, messaging and data use records. Unused account balances expire after 90 days.

Auto-pay Edit

Auto-pay can be enabled or disabled. If Auto Pay is enabled your card will be charged $15 whenever your remaining data goes below 100 MB and you have a cash balance under $2. The $15 is added to your balance to cover potential overages. If Auto Pay is disabled and your account balance is greater than $0, when you have used all of your plan's allotted data you will be charged 2.5¢ per MB overage rate until you account balance reaches $0. You must have at least $5 in your account to turn off auto-top up. If you don't you will see a warning advising you that if you turn Auto-top up off you will be charged $5 which will be added to you balance.


These data packages are sold for pay beyond the free allowance for all plans. Default rate is 2.5¢ per MB:

  • 1 GB: $ 13.99
  • 2 GB: $ 24.99
  • 3 GB: $ 31.99
  • 4 GB: $ 39.99

Data include tethering / hotspot use. Plans automatically renew every month with plan and usage fees charged to your credit or debit card. If the charges are declined service will be suspended.

There are lots of add-on services for pay like data rollover ($3.99/month), usage alerts ($1.99/month), a special hotline support ($3.99/month) and many more that you may have to decline or disable.

Free plan Edit

To use Freedom Pop for free make sure that you have completed these tasks:

  • disable all extra cost services on your online account page
  • turn-off auto-top (for this you must have at least $10 in your accout, what you don't have as a new customer
  • downgrade your promotional paid plan to the free plan on your online account page where it's well hidden. Again, for this you must have at least $2 in your account

Freedom Friends Edit

FreedomPop allows users to earn up to 500 MB per month by connecting with FreedomPop friends. You can invite anyone to join FreedomPop and if they do, you both get an extra 50 MB per month from each friend up to a maximum of 500 MB per month. On social media users share their email addresses so that other users can add them as Freedom Friends. It only takes a few minutes to gather up 10 email addresses and enter on the Freedom Friends page on the FreedomPop site for a quick 500 MB per month boost. It's a good idea to use a dedicated or disposable email address as your FreedomPop account email to avoid exposing your primary email to the world.

Another benefit of Freedom Friends is that you share data with them, up to 100 MB per friend with a maximum of 500 MB shared per month. If you are running out of data you can ask a friend to give you some using a link on the FreedomPop site.
