How do I activate a data only (internet) SIM? It keeps demanding my tmobile phone number and telephone ID number, which I don't have. This is a prepaid data (internet) SIM, which I will use in a hotspot device. Every time I try to find a way to activate this SIM online, it demands a phone number, which I don't have, because this is a data SIM. I try to "message" support, and again, it demands a T-mobile phone number, which I don't have. It really shouldn't be this difficult. Thanks for any links/help.
