I attempted to switch from Verizon to Tmobile due to their international rates. I am military and Tmobile offers great rates in Qatar. I was told that my Galaxy S6 would work by a Tmobile Rep, and ordered SIMs under the Bring your Own Device plan. I was informed that I could receive a full refund within 30 days by the rep on the phone if I changed my mind. I received the SIM cards, and learned that my Verizon variant S6 wouldn't support data services on the Tmobile network; from what I gather my location relied on a Band that they didn't provide? Regardless, I closed the account and asked for a refund on the SIM cards. I was initially told by a customer service rep that they would not refund the SIM cards. After reviewing the information I received when I initially began the process of switching and noting that it did say I had 30 days to get a full refund, I called back and was informed that I would receive a refund for the SIM cards (that was after being bounced around several times to different reps and eventually their orders department. I was informed not to worry about returning the SIM cards, because it wasn't economical for Tmobile to reuse them. I was told that I would receive a refund for the SIM card purchase. This has never happened. I have interacted with them over the phone and on chat numerous times, and been given the run around every time. I am disputing the charges with my credit card company based on the chat logs I have promising a refund, and I am also posting to this and other forums in the hopes that prospective customers will see it and stay away from Tmobile. My goal is to cost them at least as much in revenue from a potential customer as they have effectively stolen from me. So, if you're reading this, please take my advice and stay away from Tmobile. They ripped me off, and they might do it to you as well.
