MOBILE SIM

Mobile Networks in USA

There are three major Wireless Operator in USA. Verizon (Only CDMA), AT&T (GSM) and T-mobile (GSM). Rest anyone who is selling you a SIM card is what is known as an MVNO (Mobile Virtual Network Operator). They are virtual operators using the physical network of the above three operators. Usually, MVNO’s are cheaper than AT&T, T-mobile as they buy data, voice and text services in bulk from these operators and pass the benefit to consumers. AT&T and T-mobile are equally good but T-mobile has a slightly better network, especially in remote areas.

Here are few MVNOs that can be good for your stay and provide the same connectivity as AT&T and T-Mobile will provide:
