2) Clear Phone Cache Memory

If you don’t know what is the use of cache memory then in short, let me explain. Cache memory in the mobile is used to speed up mobile speed.

When you open any app, your phone processor makes a cache memory file for that app, and the next time when you open that app, the processor opens that app from the cache so it takes less time to open.

But recently in a few devices like Samsung galaxy note 10, mobile data not working problems occur due to cache memory issues.

There may be some problems with cache memory settings so cellular data, and not working problems occur in Samsung devices.


The Best way to clear the cache memory of the mobile phone is to remove cache memory from the recovery mode of the phone. There are many articles on the internet on how to clear cache from recovery mode. You can read that article and remove the cache from mobile phones.

Also, there is no internet access when airplane mode is activated.

When you turn off Airplane mode then the mobile network starts the process to connect with the network operator. In this process, all network services are refreshed so if there is any problem with the network that may be resolved. Now your mobile data starts working fine.
