I have a RUT240 being used in its simplest form - factory reset / new admin credentials and wifi passwords set up / sim installed - up and running. The problem is that while internet access if perfect I am getting no push notifications through it. 2 separate android telephones both behaving the same (and they both work perfectly when connected to a conventional home broadband wifi / router)
No notifications come through on whatsapp / gmail / doorbell app, until you either go into the app and check manually, or switch from wifi to 4g on the phone… then the whole lot come through all at once.
Incidentally if you whatsapp one phone to the other, the sending phone doesn’t even show the message as ‘delivered’ until the receiving phone either goes to 4g or you open the app manually then you get 'received / read both at once.
The sim provider says it’s not their sim causing it and i know the phones are fine…so…
any ideas that anyone has would be great to hear.
