As it's difficult for travelers to order online and have a SIM shipped internationally, I've limited this post primarily to SIM-only offers that are widely available at US retail outlets.
In order to use your phone in the US with a local SIM it must be unlocked and support the US frequency bands, which are different from those used in most of the world.
The two national US GSM operators are T-Mobile and AT&T. T-Mobile has slightly lower prices, but AT&T covers more of the country than T-Mobile. If you are sticking to major cites, T-Mobile should be fine but for extensive land travel I recommend AT&T.
coverage map, current offers) uses the 1900 mHz band (LTE band 2) for 2G , 3G and 4G LTE, the 1700 AWS band (LTE band 4) for 3G and 4G LTE and the 700 Mhz LTE band 12 for LTE only.
To get started with T-Mobile you need a T-Mobile Prepaid SIM Card Activation Kit which includes a SIM and a single use activation code. The code is required to activate a prepaid account. Do not buy an un-activated T-Mobile USA SIM on Ebay, etc. unless it includes a prepaid plan activation code. Without an activation code the SIM can not be activated on prepaid.
The easiest way to get a T-Mobile SIM is at one of the thousands of company owned stores (store locator) throughout the country. At T-Mobile shops a SIM costs $20 but is sometimes free if you activate a $40/month or higher monthly plan. Some branches of the chain electronics and department stores Best Buy, Target and Walmart also sell T-Mobile prepaid SIM kits for around $10. T-Mobile SIM kits are also available at independent mobile phone shops at prices ranging from free with airtime purchase to as much as $25. Unlike in much of the world, SIMs are not generally available at US drugstores or newstands.
T-Mobile Tourist Plan: Beginning June 12, 2016, T-mobile stores will offer a special tourist plan targeted at international visitors. The tourist plan costs $30 which includes a free SIM. It provides three weeks of service with 1000 domestic voice minutes, unlimited domestic and international text messaging and unlimited data. The first 2 GB of data is full speed, after 2 GB speed is throttled to 128 Kbps or less. 200 MB of domestic data roaming is also included. the tourist plan is good for three weeks and is not renewable.
T-Mobile Pay As You Go Plan:
Monthly charge: $3, includes 30 non-rollover minutes or texts. Additional minutes and texts (incoming and outgoing) are 10¢ each, MMS are 25¢ each
Data on the pay as you go plan is only available in the form of two add-on data packages;
- $5 for 500MB good for one day.
- $10 for 1GB good for 7 days.
T-Mobile Monthly Plans:
|Price||Talk Minutes||Texts||Included Data|
|$25/mo||unlimited||unlimited||data not available|
|$30/mo 3||100 (overage 10¢/min)||unlimited||Unlimited (throttled 1 after 5 GB/month)|
|$40 Simply Prepaid||unlimited||unlimited||Unlimited (3 GB/month high speed) 1, 5|
|$50 Simple Choice 4||unlimited||unlimited||Unlimited (throttled after 2 GB/month) 1, 5|
|$50 Simply Prepaid||unlimited||unlimited||Unlimited (5 GB/month high speed) 1, 5|
|$60 Simply Prepaid||unlimited||unlimited||Unlimited (10 GB/month high speed) 1, 5|
|$65 Simple Choice 4||unlimited||unlimited||Unlimited (throttled 1 after 6 GB/month) 5|
|$80 Simple Choice 4||unlimited||unlimited||Unlimited (throttled 1 after 10 GB/month) 5|
|$95 Simple Choice 4||unlimited||unlimited||Unlimited, Un-throttled 5|
3 $30/month 5GB plan is available only when activating a SIM or phone purchased at Walmart or when activating a new SIM at www.t-mobile.com/PrepaidActivation. If you switch to another plan you can't switch back to the $30/month unlimited data plan.
4 For BlackBerry users there's a BIS add-on available at no extra charge on $50/month and higher Simple Choice plans.
5 Tethering and hotspot are permitted on Simple Choice and Simply Prepaid plans, Hotspot/tethering are throttled after 14 GB on the $95 unlimited Simple Choice plan
The best deal for most visitors is probably the $30/mo 5GB, 100 minute, unlimited text plan. It's also the hardest to get as it's only available for online activations or with SIMs or phones purchased at Walmart. Unfortunately T-Mobile stores are prohibited from selling the un-activated SIM kit needed to activate online. SINs purchase online from T-Mobile come preactivated and can't be switch to the $30plan either. You can get around that by buying a SIM kit before your trip from an eBay seller who will ship internationally or at Best Buy, Target or Walmart store after you arrive in the US.
The monthly plans automatically renew every 30 days providing you have sufficient funds in your T-Mobile account. You can switch between monthly and pay as you go plans (except for the $30 unlimited data plan) by calling 1-877-778-2106 on any phone or 611 on your T-Mobile phone or by using T-Mobile's mobile (ma.web2go.com) or desktop (my.t-mobile.com) web sites. Plan changes from or between plans go into effect at the end of the plan period by default but customer support can make an immediate plan change on request.
Hotspot and tethering: allowed on all plans. Hotspot/tethering are throttled after 14 GB on the $95 unlimited Simple Choice plan.
Domestic Roaming: T-Mobile allows voice and text roaming at no extra cost on a number of regional operator's networks (areas labeled as "partner" on T-Mobile's coverage map). There's limited data roaming on "Simple Choice" monthly plans $50/mo and higher. Roaming on the $50 plan is limited to 10MB/month, $60 and $70 plan users get 50MB/month of data roaming. On other plans data roaming is not available
International calling and messaging:
T-Mobile Simple Choice plans include unlimited calls to Canada and Mexico. Unlimited Mexican and Canadian calling and roaming can be added to Simply Prepaid plans for $5/month.
T-Mobile offers two "Stateside" international calling add-ons which are available with the $50, $60, $70 and $80 monthly plans only:

MVNO Alternatives. AT&T and T-Mobile are the only national US GSM operators, but there are dozens of Mobile Virtual Network Operators (MVNOs) in the US that resell service from either AT&T or T-Mobile. MVNO SIMs are sold online and by independent mobile dealers. MVNOs typically have lower rates than T-Mobile or AT&T but SIMS can be hard to find.
Here's a sampling of some of the better MVNO deals.

Global SIMs: There are many brands of global or travel SIMs which are work in multiple countries. Global SIMs are convenient but rates tend to be high. The best global SIM for US visitors is from Truphone. Truphone is pay as you go and US rates are 9¢ per outgoing minute or text and 9¢ per MB of data. Incoming calls and texts are free. Truphone uses both the AT&T and T-Mobile networks as well as some regional networks in the US. Truphone SIMs are sold in the UK, US, Australia, Hong Kong, Netherlands, Germany, Poland and Spain. In the US they cost $29.99 and include a $15 airtime credit. There's no requirement to top up regularly, pay as you go credit never expires as long as you make a call, send a text or use some data at least every 90 days.
Recommendations T-Mobile and T-Mobile MVNOs tend to be less expensive than AT&T, especially if you need lots of unthrottled data per month. T-Mobile's coverage is inferior to AT&T's but T-Mobile works well in all major cities and provides at least 2G coverage along most highways.
If you demand the best possible coverage with 3G and 4G data speeds in the most places, AT&T is the best choice. The least costly option that includes data is the $30 Monthly Plan with a $5 - 100 MB data package. The $60/month unlimited plan with 4 GB of high speed data is a better choice for serious data users
Buying a SIM and service at an AT&T and T-Mobile store near your hotel is the quickest and most convenient way to get mobile service in the US. However it's not the least expensive. It's possible to save money with an MVNO if you are able to buy SIMs online or are willing to spend some time to finding a dealer.
Truphone is cost effective for light use and it's convenient, especially if you can buy an activate a SIM in your home country before leaving for the US.
