The service worked well
The service worked well in Ho Chi Minh and in Ho Anh/Da Nang but very intermittently in Hanoi. I reached out to Sim Corner but I reverted to using WiFi when I lost service.

I got into difficulties
I got into difficulties opening the new sim on arrival becauseyou need to follow the instructions very carefully with an e sim. The Simcorner team did a brilliant job helping me all the time I was in the hotel on their Wi-Fi. All is good now. But I have learnt a lesson- do not rush!!

Good idea
