Hi there @andyjhunter. i’d be happy to help with this messaging issue! this is a somewhat recurring bug for some iphone users. to resolve this issue: take down the affected number, as we’re going to delete it from the device. I need to know what to do about iphone error invalid number when texting. use the right phone number when sending the text. it is the right phone number.. Please resend using a valid 10 digit mobile number. i was able to send texts and call my friend in norway, and then, after one of the ios updates, my phone no longer recognizes the international phone number..
I bought my wife a new iphone 5s for mother's day. she of course loves it, but informed me that she was unable to message me and kept getting the following message: message sent using invalid number of digits. please resend using 10 digit number or valid short code. msg 2114. our carrier is sprint. At&t employee here: no root necessary!!! whiteout has the correct solution (apart for deleting cache).this is happening because your t-mobile visual voicemail app is continuously trying to get in touch back with t-mobile to see if it has any voicemail messages.. If you still see the error, check for other usb issues, check your third-party security software, then check your hardware. if you still see an error, contact apple support . check your hardware.
