S21 ultra Data issue

[raviaga]

I have been using S21 Ultra For around 150 days now. The phone is good, we love it. The major issue which I have seen is of Mobile data. The mobile data suddenly stops completely. Here is the poc for reference 

The mobile data get stuck like this and this happens frequently. I have to toggle flight mode and again to get internet back.

 The mobile data works well but this issue is too frequecnt and completely ruins the user experience. If you need a stable Internet connection then this is a big trouble.

 I have used same Sim and network in Galaxy Note 20 and FE but haven't face thiis issue. I have done, Network settings reset, changed sim and even did hard reset but this issue is always there. I have talked to customer care multiple times but they arent able to sovle this. This issue also remains in SAFE MODE. There is something which Samsung needs to fix. I have seen others users complaining for the same. This issue might be OF LTE /4G Receiver but 3g working fine but I haven't witnessed this in Other phones. 

 I don't know if I will get solution for this or not but if you are buying S21 Ultra do note you might also get this issue. Also I am open to any suggestions which you might have for this issue apart from the things whi I have already mentioned. We tried to visit all from our end. Last and final is switch to IPhone. Thank you Samsung u have care about your premium customer.

Its not the issue with sim or network.

I am also facing the similar issue on s21+ and the kinda solution is using a single sim instead of dual. Just remove the second sim from the device and than check. It worked for me. Though it is not a perfect solution but it might help

But then, what's the means of dual sim phone and that to premium phone

True dear. I agree, m also experiencing the same problem

SIM 1 should be used for Data. I too was getting no internet error in multiple apps even Google Maps. It resolved automatically on its own after 2 days.

Same issue was faced by me on airtel network in s20. It is the issue by network provider. Replace the sim card.
