Notifications only arrive when connected to wifi

I have been experiencing this exact same issue on my Pixel 7, but found the content filter was already deactivated.

Instead I tried adding the Smarty APN settings again (as a brand new entry, not editing the existing entry) and this seems to have helped.

I just noticed the same is happening with me.

I'm thinking it's a Smarty network issue, maybe?

Really shocking service from Smarty support team. After switching from a different network, I had the same issue with my Samsung Galaxy too. Two days and 10's of emails, none of the support team could give me the right solution. They asked me to do so many other things and now my phone is in a messy state (factory reset tonight). Most of them are incompetent and don't even read my emails properly. The correct solution to this issue is "Adult content filter" off, good luck all.

This problem is the reason the Emergency test did not work on Sunday.

I've found a fix

Go to setting, then go to connections then go to data usage and then go to data only apps and add turn the apps on

Has anyone found a fix to this yet? I've tried everything including resetting my phone and nothing has changed. My APN is set to mob.asm.net as it should be. Notifications permissions given but still nothing 

I have recently experienced this issue again as well. It doesn't seem to be consistent on Smarty - it must depend on when they decide to 'fiddile' with their content filter, or perhaps if there is congestion on the network.

Turning off the content filter works. I don't have this issue on a Three Mobile SIM I have (but that SIM obtains a Public IP address and doesn't sit behind CGNAT like all Smarty SIMs)

yes I can confirm, switching off the adult filtering solves the problem. No way I am going to bring over my family now to smarty if they all have to remove the adult filter. Such a shame really.

Any tech from smarty reading this, sort out your adult filtering, it's blocking push notifications to many apps like Gmail and Whatsapp

Hi just in case this has been missed if you go into apps in settings me use click on the apps you wish to use woth your mobile outside your home not on WiFi and make sure the permissions are set to the correct. 

Also make sure data only usage is set up on your phone for each app you want to use in the background but beware this can use a lot of your data up with apps that are using your mobile data without reliance upon WiFi so for instance you want your security camera running on mobile data so your ring app has to be turned on to use mobile date in the background and say you use amazon or ebay but not while your outside much turn them off using your mobile data as background processing and apps even android or apple apps that are configured for the phone they will use data without you releasing. 

I always go to my apps and turn of apps I dont use even games run background usage of mobile data in background, and if your not on a unlimited plan for data then you will will be out of data quicker than the ride home from the shops.

You can always go into setting and set up DATA WARNING so say you had 8gb of data you type 8gb date of the month you brought it or it came in to action on your device and it will remind you when your 80% out of data.

Also even on unlimited data networks don't tell you that if you are abusing data and even some if your not will slow you down once you reach 100 gb no network will give you the speeds of your data once you reach a data level as in all it cost them money and they are a business

Hope that helps

Forgot to mention, the solution also resolved the same issue on my wife's phone.
