Re: My phone has stopped receiving text messages lumia 630
It may be an issue with your carrier or your SIM card.
If you can send SMS, there is no fail message and recipients can verify they did in fact get the text, then your phone is configured properly and it is not hardware/software related to your handset.
SMS text lag is a known issue and is usually carrier side. I would consult with them and ask for A) a re-provision or B) a new SIM
Provisioning is when your account accesses are granted carrier side. On CDMA it is one method, on GSM another... A Re-Provision is the resend of those authorizations to where they reside in the system. A do over. LOL. To get a reprovision done usually requires escalating up the ladder in tech support. Most customer service types will have no clue what you are talking about. Request a help ticket and get the escalation process started.
