I switched my mother over 1.5 yrs ago. I had to call customer service for her renewal and getting a new phone -they blatantly lied to me (resulting in extra charges) and charged my card without permission when I wasn't even on the phone (using a card I had in their system). I spoke to a different customer service rep on another day who told me completely different things and laughed about the 1st one lying to me. She clearly knew that the other rep would have lied to me about these charges.
Unsurprising.
Reddit is full of people who say they love it right until they have to interact with customer service and that customer service has gone down fast.
You can't really go "down" from rock bottom, been this way ever since they were founded and known as Mint SIM. They're only nice to new customers, the nice only lasts until you actually need customer support for real problems, and of course the bulk sales model lends itself well to the cash grab and bait and switch... add the insult that it's on one of the weakest of the major networks with the funkiest spectrum divisions and coverage holes? This is why I never recommended them in the first place back in the Guide days here.
And I've not really talked about it much, but during that era when I maintained the guide website, I used to get harassment and ugly, insulting comments left by people posting from an IP address block owned by Mint, and self-reporting as employees for pointing out those problems and refusing to recommend them, calling me every name in the book for it... and that was during the era that Ryan Reynolds had gotten involved in advertising but before ownership stake... which is why I have a really hard time believing his "nice guy" act. Dude had to know exactly what he was buying into. The Mint subreddit's always been awash with horror stories from customers. The harassment magically stopped right after dumping the pile of evidence in an email addressed to their systems administrator, and CC'd to their customer support and legal departments, despite hearing nothing back from them in response.
I'm glad it's worked for some here, and they haven't run into problems... but it's definitely not an expectation of normal that I'd expect.
But the thing to understand is that the prices and packages they're offering are not unique and never have been. You can get competitive pricing and better network options without near as much support drama from outfits like Red Pocket... which is again why when I stopped doing the guide, I just recommended them as the first line stopping point. US Mobile now also fills a similar slot now that they're using all three networks as well.
