I managed to solve the issue! Here’s what worked for me:
- APN: It’s recommended to check with your SIM card provider for the correct APN settings.
- TTL (Time To Live): Set this to 65, 88, or 117.
- MTU (Maximum Transmission Unit): Use a value lower than 1500, such as 1420.
With these settings, everything worked as expected. Hope this helps someone else!"
This gives clear guidance for others facing the same problem.
