Mobile Data Keep Alive App

[eznoh]

I have a couple of Samsung Galaxy S9s with an annoying problem. Mobile data will often not work until I toggle airplane mode. Supposedly this causes the phone to find the strongest signal. I checked with Samsung and they suggested many things to try none of which worked. I'm wondering if an app exists which runs in the background and periodically checks if mobile data is active and if not connects

Head over to your system settings and check underneath battery

That be it, the battery optimizer.

Don't see battery optimizer. I see Power mode and App power mangement

It was set to Optimized. I set it to High performance but it made no difference. Also under App power management I tried turning off adaptive battery and put unused apps to sleep but it made no difference

I've given up on this phone. Can anyone recommend a similarly priced replacement (~$500) that will do 5g? One I'm considering is the Motorola Edge.
