Create stable internet connection

I connect to GSM and after few seconds its gets disconnected automatically
Interface: rmnet_data0
Family[IPv4]: inet
Dns2[IPv4]: N/A
I got this Connected but Dns2[IPV4] didn’t get the IP so to do this I have to restart the radio
Any hints how I can make it stable.

Have you checked the signal strength?

How is the reproducibility?

Power: ON
Current Network Operator: vodafone UK
Current RAT: LTE network (LE_MRC_RAT_LTE)
Status: Registered, home network (LE_MRC_REG_HOME)
Signal: Strong signal strength (4)
PS: Packet Switched Registered, home network (LE_MRC_REG_HOME)
Signal strength looks fine to me?

Yes, but this is lte, not gsm

You said you connected gsm …

It was my bad actually it is connected LTE network.

How is the reproducibility for not having dns2?

Its not so often but sometimes it does.

Then maybe it is network problem

Have you checked with network operator

I have not checked with network operator but will do now.
