Hello,
So, you have enough data remaining in your sim card .
Could you please share me a troubleshoot file for the device when the vodafone sim card is inserted .
System>Administration>Troubleshoot.
Also you have tried keeping auto and manual APN and its still not working properly. May i know if you have confirmed with the ISP what is the correct APN.
What IP does acquire , what IP address you are receiving on your sim is it public or private ?
As you mention that the other network sim card works fine but issue is only with vodafone. So, meaning device is working fine . Only issue comes when you use vodafone so may i know if vodafone has good coverage in this area?
Have you tried to relocate device to receive more better signals.
