Carrier Aggregation not working

[Rishav188]

I am using S21 unlocked version (Snapdragon 888) bought from USA for the last 9 months.

But I have noticed that Carrier aggregation (LTE+ / LTE-A/ 4G+) isn't working since the beginning. 

I'm currently on Jio, I've tried the same sim in another Indian model S20FE, where I get carrier aggregation without any issues.

I've tried all possible ways available on the web, including changing bands using Samsung Band Selection app. But nothing seems to be working.

I'm stuck with a $950 phone with lower data speeds than on a $200 phone. 

Please help and other S21 USA unlocked users, share your experience and opinion.

One of the perils of importing a phone not meant for your country. People have reported this earlier too,along with issues like lack of call recording (when imported from Gulf) etc.

Check whether the smartphone supports international SIM card

It supports. I've used Sim cards from South Korea and Panama when there. So yes, international sim works fine. But LTE+ isn't available.

May be your operator or your area have some problem
1. Use Airtel or vi for check ca( From friends or family)
2. Check network coverage in nearer city or town

Same Sim works on LTE plus on S20FE 5G in the same place, connected to the same network tower. So not an issue of the sim most probably.

Bro it's restricted because of region change or something. Unfortunately none of the users who imported a device from Samsung could find a solution as far as I know. Please let us know if you find any workaround.
