I've been using US Mobile and it was great until they just switched me to a different plan that is the same price but ever since I've had issues placing calls... to family, to businesses, anyone. I also can't get it check voicemail. SMS works and MMS is spotty but LTE data is fine on my 7a.
Does anyone have any recommendations? T Mobile is not strong enough in my house (tried Mint Mobile last year) so that's not a great option but up for most anything that lets me call, too.
