Straight Talk is a Mobile Virtual Network Operator (MVNO) offering both CDMA and GSM support. The CDMA service uses Verizon's or Sprint's CDMA 1xRTT wireless networks and the GSM service makes use of either T-Mobile's or AT&T's GSM networks.
Straight Talk has a joint-venture agreement with Walmart that makes Walmart its exclusive retailer, though customers can buy phones and service directly from Straight Talk via its website or by telephone.
Straight Talk offers several different rate plans. Depending on price, these deliver limited or unlimited service over a 30-day period. Monthly prices are reduced when plans are activated with Auto-Refill, which automatically activates the same service plan once the 30-day period is complete. High-speed data is unlimited on the $55 Ultimate Unlimited Plan, and it is limited on the $45, $35, $30 and $10 plans, with speeds lowering to 2G after stated data allotments.
Service plans do not include hotspot tethering. Video streams at up to 480p. Straight Talk customers' speeds are prioritized behind customers on the network they are using during times of congestion.
