TCP keepalives disconnect 3G

[Edwe]

I'm am using a 60+60 prepaid bundle in a Huaweii E1752 plugged into a Billion BiPAC 7300NX WiFi router. I have noticed that my connection disconnects after the exact time duration I set for the router's TCP keep-alive. If I disable keep-alive completely, the connection stays up.

Could it be that TM is deliberately kicking devices which send keep-alives? It's kinda annoying and didn't happen until about a month ago, and still doesn't happen with an MTN SIM. Took me hours to track down the problem.

Good day. Thank you for your offer. I think I may have left out some info: I tried this on two different TM SIMs and it seems to be a network policy thing, and not a problem with a specific number. To verify, I put the SIMs in a different device with keep-alive and the exact same thing happened. I have already resolved it on my side, and don't require individual assistance.

I would rather just like to see a public answer as to whether the TM 3G network, by design, kicks devices which send keep-alives.

If it is a policy thing, which I believe is likely, it would be useful to make it known to everyone on the forum, because it would affect all 3G routers which have a keep-alive feature.
