for the T-Mobile plans, prepaid, postpaid, business, etc. the SIM's work perfectly fine in phones, including ones know to T-Mobile such as there branded phones. my plan explained on the other thread is to use my SIM in a phone not a tablet.
it is just that they are 'intended' for tablets. in some activation situations you may need to provide a tablet IMEI for initial activation to get the plan options to populate. on the business activation site you can skip the IMEI step and than select 'tablet' as the type of device you are ordering the SIM for. no restriction after on the the device used in except may not work in dedicated hotspots or home internet modems, some are reporting success even in those type of devices though.
ATT tablet plans also generally work in many/most phones although I do believe its a TOS violation and some people have been notified they need to put the SIMs back in the correct device type.
