Upgraded my phone from oppo to S21. Happily exploring this new gadget , however, ended up will keep loading when do browsing. 
I then use the same sim card to return to Oppo. The Same location, oppo has no issue of browsing but the S21 is suck.

 A 5k gadget and end up cannot use as smart phone. What else left?

Any solution?

It might be also because oppo support budget bands while samsung support high end bands because each phone's supported bands vary
