Note 3 running kitkat 4.4.2, purchased through T-mobile. I unlocked and inserted a Consumer Cellular sim. Wi-fi calling is no longer supported but the main problem is, I receive multiple, repetitive texts from +1121611611 reading: 122 Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code. [and then a string of numeric characters] Consumer Cellular says their stuff is working right, even though I'm pissed at them bc they told me wifi calling would still work and it doesn't. Apparently unlocking a phone has some issues. T-mobile says they are not sending these texts. They suggest I have an unsent text somewhere that keeps generating the same error message, but I can't find one, and was not texting when this started happening. I receive this text message every time the phone is powered on, and sometimes several more during the day. I've received six of them so far today, and counting. Appreciate any clue how to stop this!
