I will be staying in Houston (Texas) for about a month and I'm looking for a prepaid SIM card that I can use during that time, preferably with mobile data.
Update (more details):
Primarily, I'm looking for data transfer. Voice calls are secondary, in fact, I could do without. I will be staying at the same hotel throughout the duration, so if the coverage area includes Houston that's good enough.
Most recent time I did this I got a 1-month prepaid SIM card from T-Mobile. I think was something like $70 with tax and a SIM card to fit my phone. There was a couple G of LTE data and some phone time. Pretty painless- maybe 5 minutes in the shop. Here are their current rates. It worked out okay, but coverage was a bit spotty outside major cities. The data is 'unlimited' but throttled back to 3G speed over the total data limit.
AT&T has similar plans, however the T-Mobile prepaid plan allowed tethering, which was a requirement for me (that's when you link your laptop with your cell phone and use the cell phone's mobile data connection to allow your laptop to access the internet). AT&T required a contract for that feature.
