The problem with not being able to send double-digit numbers or lengthy messages could be related to phone settings, network issues, or how the messages are being encoded and split. A potential solution that has worked for other users is to try turning off "chat features" or Rich Communication Services (RCS) in your messaging app's settings, as these features can sometimes interfere with standard SMS messages.
Here are some troubleshooting steps that may help resolve the problem:
Check Messaging App Settings: Go into your messaging app's settings and look for a feature called "Chat features" or "RCS." If it's enabled, try turning it off.Verify APN Settings: Ensure that your phone's APN (Access Point Name) settings are correct for Tesco Mobile. Incorrect settings can prevent messages from being sent.Check for Network Issues: Confirm that you have a strong signal. Try turning airplane mode on and then off to reset your network connection. You can also check for any reported network outages in your area.Restart Your Phone: A simple restart can often resolve temporary software glitches that may be causing the problem.Clear the Cache: Clearing the cache for your messaging app can fix corrupted data that might be preventing messages from sending.Update Your Phone's Software: Make sure your phone's operating system is up to date, as this can fix bugs and improve functionality.Contact Tesco Mobile: If the problem persists after trying these steps, it is recommended to contact Tesco Mobile's customer service again, as it could be a carrier-specific issue.
