I have 4 lines with cricket, 2 are actual cricket phones and neither of them are able to use wifi calling. Keep getting the oops error message after we enter the address. I've contacted support several times and they have been unable to resolve. I went to the store and got a new Sim card for on of them and that didn't work either. More than a little frustrated at this point. Not sure what the problem is, we've checked the IMEI number, checked the address. Any other ideas?
