<P> T - Mobile USA has a similar clause in its "Terms & Conditions": </P> <P> Unless explicitly permitted by your Data Plan, other uses, including for example, using your Device as a modem or tethering your Device to a personal computer or other hardware, are not permitted . </P> <P> T - Mobile's Simple Family or Simple Business plans offer "Hotspot" from devices that offer that function (such as Apple iPhone) to up to 5 devices . Since 2014 - 03 - 27, 1000 MB / month is free in the USA with cellular service . The host device has unlimited slow internet for the rest of the month, and all month while roaming in 100 countries, but with no tethering . For $10 or $20 / month more per host device, the amount of data available for tethering can be increased markedly . The host device cellular services can be canceled, added, or changed at any time, pro-rated, data tethering levels can be changed month - to - month, and T - Mobile no longer requires any long - term service contracts, allowing users to bring their own devices or buy devices from them, independent of whether they continue service with them . </P> <P> As of 2013 Verizon Wireless and AT&T Mobility offer wired tethering to their plans for a fee, while Sprint Nextel offers a Wi - Fi connected "mobile hotspot" tethering feature at an added charge . However, actions by the FCC and a small claims court in California may make it easier for consumers to tether . On July 31, 2012, the FCC released an unofficial announcement of Commission action, decreeing Verizon Wireless must pay US $1.25 million to resolve the investigation regarding compliance of the C Block Spectrum (see US Wireless Spectrum Auction of 2008). The announcement also stated that "(Verizon) recently revised its service offerings such that consumers on usage - based pricing plans may tether, using any application, without paying an additional fee ." After that judgement Verizon release "Share Everything" plans that enable tethering, however users must drop old plans they were grandfathered under (such as the Unlimited Data plans) and switch, or pay a tethering fee . </P>
