Push notifications on mobile data (A5 2017)

[wooser]

Hi!

I have a problem with push notifications. I don't receive notification when i use mobile data connection (network working). When i use WiFi i got all notifications. Sometimes solution to receive notifications from apps when i use mobile data is turn on airplane mode and turn it off > then i got notifications. What's wrong? ROM bug for this phone? I flash new official Samsung ROM with full wipe and this not solved my problem.

Who is the carrier it sounds like a possible data issue, I can get push without problems

Probably on old phone all works correctly. I get new sim card for this phone (size: nano) so i think that card is ok.
i found some about this problem in google but no solution for a5 2017. One solution is airplane mode on/off.
