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 lower prices, 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 for 2G GPRS/Edge and the 1700 AWS band for 3G/4G UTMS/HPSA/HPSA+. Very few non-US phones support the AWS band.
In most major cities, T-Mobile also has 3G on the 1900 Mhz band that most non-T-Mobile phones, including older (pre iPhone 5s) iPhones do support. 1900 Mhz UTMS/HSPA+ is available in the following markets: Anaheim, CA, Ann Arbor, MI, Atlanta, GA, Austin, TX, Baltimore, MD, Boston, MA, Cambridge, MA, Chicago, IL, Dallas, TX, Denver, CO, Detroit, MI, Fort Worth, TX, Fresno, CA, Ft. Lauderdale, FL, Houston, TX, Kansas City, KS, Las Vegas, NV, Los Angeles, CA, Mesa, AZ, Miami, FL, Minneapolis, MN, Modesto, CA, New York, NY, Newark, NJ, Oakland, CA, Orlando, FL, Philadelphia, PA, Phoenix, AZ, Providence, RI, Reno, NV, Richmond, VA, Sacramento, CA, San Antonio, TX, San Diego, CA, San Francisco, CA, Seattle, WA, Silicon Valley, CA, Springfield, MA, Stockton, CA, Tampa, FL, Tucson, AZ, Virginia Beach, VA, Warren, MI, Washington, D.C.
T-Mobile has LTE 4G data primarily on the 1700 Mhz AWS band (LTE band 4) with supplemental service on 1900 Mhz LTE band 2. T-Mobile started adding additional LTE service on band 12 (700Mhz) in the third quarter of 2014. There's a list on LTE markets on this T-Mobile Web page.
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 $15 but is often 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 Pay As You Go Plan:
Monthly charge: $3, includes 30 non-rollover minutes or texts. Additional minutes and texts (incoming and outgoing): 10¢ each
MMS: 25¢ each
Data on the pay as you go plan is only available in the form of two add-on data packages; $5 for you 500MB good for one day. A better deal for most visitors is the $10 1GB package good for 7 days.
T-Mobile Monthly Plans:
|Price||Talk Minutes||Texts||Included Data|
|$30/mo 3||100 (overage 10¢/min)||unlimited||unlimited (throttled 1 after 5 GB/month)|
|$35/mo||unlimited||unlimited||data not available|
|$40 Simply Prepaid||unlimited||unlimited||Unlimited (1 GB/month high speed) 6|
|$50 Simple Choice 4||unlimited||unlimited||Unlimited (throttled 1 after 1 GB/month) 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 $50 and higher Simple Choice plans. It's limited to 1 GB on the $50 plan, 3GB on the $60 plan and 5 GB on the $70 and $80 plans
6 High speed data on the "Simply Prepaid" plans is throttled to 8 Mbps. After the high speed allotment is used unlimited data throttled to 128 Kpps is available.
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. You can get around that by buying a SIM kit before your trip from an eBay seller who will ship internationally or at a Walmart store (Find this item at a Walmart store)
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.
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 offers two "Stateside" international calling add-ons which are available with the $50, $60, $70 and $80 monthly plans only:

MVNO Alternatives. There are dozens of Mobile Virtual Network Operators (MVNO) in the US that resell service from either AT&T or T-Mobile. MVNO SIMs are sold online and by independent mobile dealers. MVNOs 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.
T-Mobile MVNOs (Unlike with T-Mobile itself, off network roaming is not available on T-Mobile MVNOs):

- Air Voice Pay As You Go: 4¢/min, 2¢/SMS, 6.6¢/MB, $10/30 days minimum top up. Monthly plans with unlimited talk and SMS (int'l included). $30 500MB; $40 1GB; $50 2GB; $60 3GB.

Recommendations T-Mobile is less expensive than AT&T, especially if you need more than 1 Mbps 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, but it's not cheap. The least costly option that includes data is the $25 Monthly Plan with a $5 - 50 MB data package. The $60/month unlimited plan with 2.5 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.
