Really works fantastic. I am using tsim number of times and the service is exceptional. This is the first time I am using esim. I got the USA number before starting the trip in India itself and the connection started working when the flight landed in NY only. Quality of the local calls, calls to India and data is very good.

Great deal offered by tsim, worked perfectly, bought 28days 19gb version esim. Added it in India though it will not work in India but once I landed in Barcelona, Spain it started working. Was able to make a cellular call back at home and local calls as well. After each call you will get notification about how much minutes are left. The network I was getting was vodafone ES and it was good even when I visited Balearic Islands (Palma), internet connectivity was great. You cannot see how much data is left by notification in my knowledge but there is a workaround for that. If using iphone go to mobile-data and it shows amount of data used on the network.

Just the best! esim worked perfectly! free gift options are very useful! highly recommend| excellent experience, i was fearing that the esim may pose an issue but it worked very well! 24 7 customer service is also very nice. they give imeediate replies which is awesome! policy of useful free gift is cherry on top!
