Since my 81 year old brain hasn't reached the tech savvy world I contacted T-Mobile prior to purchasing a Samsung Galaxy S7 plus Tablet. I explained I was awaiting Amazon Prime day to take advantage of the significant one day discount. In response to my queries (he never asked for any further details about the tablet) he said all that was necessary was to bring it to their store for a SIM card. Due to ill health I wasn't able to leave the house for a few months. By the time I did take it to the store I was no longer able to return the useless tablet that I now found out was wi-fi only and could not be used with any phone plan. Subsequent to numerous conversations, including more misleading information, I was told they would magnanimously offer 3 months free service for my tablet. Talk about adding insult to injury... what tablet is that? Oh, the new one I cannot possibly afford to purchase to replace the useless, pricey one I already own. By the way, between Nextel, Sprint & T-Mobile I have been a customer for 20+ years, and this rude, greedy, disrespectful, ignorant treatment is a helluva way to "thank you for being a loyal customer." CAVEAT EMPTOR!
