Would like to share experience of using international sim card of Uniconnect recently to my Europe trip. I took one sim and was roaming in 4 different European countries.Connectivity was good, voice clarity n data access were decent. The best part was no need to change the sim for each new country.
Back home family was calling me daily since my incoming calls on this number were free n they were getting charged minimal.
I have purchased it online and got delivery before my travel. And I can retain this for my future travel or any of my family members can use this as sim n balance never expires.
