Samsung s21 ultra data connection drop

[AlexDcosta]

Anybody faced  random local sim1 mobile data connection drop when using dual sim in s21 ultra especially with sim2 on international roaming

[dilshan1]

Yes

[dilshan1]

Still not figure it out why

[AlexDcosta]

Are you having data drop issues even when using both local sim cards?

[dilshan1]

Yes but my one sim is roaming
And if u set 4 g mode u can use both sims

[AlexDcosta]

I dont seem to have drop issues when using both local sim cards but have issues when using one roaming

[dilshan1]

OK so I think I have to remove roaming sim

Try setting the network of the roaming sim to 2g only and check. I set mine, data seems to work fine
