Just curious. Did you try Worldsim.com's sims? I found terrible reviews about them.There are many of providers, look at the below, that just a few.
it's you decision but you should understand that this is how American websites look like - no one simply cares, business first
Yes you can, just get a $3 prepaid SIM card at any T-mobile store with no questions asked. Residency/address/etc do not matter. This $3 kit will give you 30 units/mo (any combination of 30 incoming/outcoming text messages and/or voice minutes). To keep the number you will need to replenish it with $3 every month. There is also plenty of prepaid options among numerous MVNOs - check out this great database of MVNOs: BestMVNO - Wireless News, Deals And Cell Phone Plans ComparedIf not, and if I will be in the USA, but if I'm not a US-Resident and without a US address, will I be able to get such SIM from the regular Mobile carrier companies (like T-mobile)? From who and what should I ask for? (what time of SIM)?
Did you tested this provider? Bitcoin may be good if you want to stay anonymous.
