As it's difficult for travelers to order online and have a SIM shipped internationally, I've limited this post 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 operators are T-Mobile and AT&T. T-Mobile has lower prices, AT&T covers a bit more of the country than T-Mobile.
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 2012, T-Mobile began deploying 4G HSPA+ on the 1900 Mhz band that most non-US phones, including all iPhones do support. As of Dec 23, 2013, HSPA+ on 1900 Mhz is deployed in: 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.
In 2013 T-Mobile started adding 4G LTE on the 1700 Mhz band (LTE band 4). As of Nov, 2013 T-Mobile has deployed LTE in 255 markets (list). LTE data is available to prepaid users with on any plan that includes data.
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 on line with T-Mobile is at one of the thousands of company owned stores (store locator) throughout the country. A SIM costs $10 and includes 10 minutes of starter airtime. The SIM is often free if you activate on a $40/month or higher monthly plan.
The SIM kits are also available at independent mobile phone shops at prices ranging from free with airtime purchase to as much as $20. 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 buys you 500MB good for one day. A better deal for most visitors is the $10 1GB package good for 7 days.
T-Mobile airtime refill PINs in $10, $30, $50 and $100 denominations are readily available and can be purchased at T-Mobile and independent phone shops, "big box" retailers like Target and Walmart, Office Depot stores, 7-11 convenience stores, chain drugstores such as Walgreens, CVS and Publix and at electronic retailers including BestBuy and RadioShack.
T-Mobile Daily Plans:

|$3/day 1||unlimited||unlimited||unlimited (throttled after 200 MB/day)|
T-Mobile Monthly Plans:

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 plans.
5 Tethering and hotspot are permitted on $50 and higher 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
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, daily 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 monthly plans go into effect at the end of the plan period.
Domestic Roaming: T-Mobile allows voice and text roaming at no extra cost on a number of regional operator's networks (areas in yellow labeled as "partner" on the coverage map). There's limited data roaming on 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 $30, $50, $60, $70 and $80 monthly plans only:
- $10/month unlimited calls to landlines in 70+ countries, reduced international rates to 200+ countries
- $15/month unlimited calls to mobile phones in 30+ countries and landlines in 70+ countries, reduced international rates to 200+ countries.
Unlimited international texts are included at no-extra charge on the $30, $50, $60, $70 and $80 monthly plans and cost the standard 10¢ each on all other plans MMS are 25¢ each on all plans.

coverage map, current offers) uses the 850 and 1900 mHZ bands for GPRS/Edge. 3G UTMS and 4G HSPA+. Most areas have both 850 and 1900 coverage but some are 1900 only (map).
LTE data is available to prepaid users. AT&T mainly uses band 17 (700 Mhz) for LTE but also uses bands 5 (850 Mhz). 2 (1900 Mhz) and 4 (1700 Mhz) for supplemental LTE service in some urban areas.
AT&T uses the brand AT&T GoPhone to refer to its prepaid services.

AT&T stores charge $10 for a SIM although this is generally waived if combined with an airtime purchase. There is a 0.20 to $1.50 monthly 911 fee charged in some states in addition to applicable state sales taxes.
International calling and messaging:
A $5/month International Long Distance Feature Package is available that provides 250 minutes of calling to over 50 countries (list of countries).
There's also a $10/month Mexico Long Distance Plus package can be added to $50 and $60 monthly plans only. It includes 1000 minutes of calling to cell phones and landlines in Mexico, Canada, India, China and several other countries and to landlines in over 50 countries (list of countries).
Without an international add-om. AT&T's voice rates are better than T-Mobile's but are still high. Calls to the UK and most Western European countries cost $0.49 per minute, for India, Australia and Japan the surcharge is $1.09/min.
Unlimited international texts to 100 countries (list) are included with the monthly and $2 daily plans. On pay as you go international texts are 25¢ each to send and 20¢ to receive.
As with T-Mobile the easiest way to get a SIM and pay for service is at an AT&T corporate store (store locator). AT&T's prepaid coverage area (map) is larger than T-Mobile's but AT&T doesn't allow voice, text or data roaming on prepaid plans.
Refill PIN cards are widely available at AT&T and independent phone shops, "big box" retailers like Target and Walmart, Office Depot stores, 7-11 convenience stores, chain drugstores such as Walgreens, CVS and Publix and at electronic retailers including BestBuy and RadioShack.

MVNO Alternatives. There are dozens of Mobile Virtual Network Operators (MVNO) in the US that resell service from 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 T-Mobile proper off network roaming is not available on T-Mobile MVNOs):
- Ptel Pay As You Go: 5¢/min, 2¢/SMS including international, 10¢/MB, $10/60 days minimum top up. Monthly plans with unlimited talk and SMS (int'l included). All include unlimited 2g (128 Kbps) data: $25/month 2G data only; $35/month 500MB 4G; $50/month 2GB 4G. Low international calling rates. Dealer locator

Recommendations I consider T-Mobile to be the best choice for most visitors, especially for stays of 20 days or less. $25 at a T-Mobile store buys you a SIM and $15 in call credit. Activate on the $2 or $3 per day plan for 5-7 days of unlimited talk, text and data. 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 GB of 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.
Another easy, relatively cost effective option, especially for short visits, is Ready SIM, a T-Mobile MVNO that sells SIMs preloaded with a 3 day, 7 day, 14 day or 30 day plan. Ready SIM's Amazon storefront offers worldwide shipping for about $10. All plans include unlimited talk and text, including international texting. Plans with or without data are available. A 7 day ReadySIM with unlimited talk and text and 500 MB of data costs $25.
