MattData SIMAug 02, 2026Recognises 2nd gen residence card
It was very quick and easy to order a SIM card and pick it up at their office the next day. They allow you to pay with an international card, and they have updated their systems to recognise the 2nd generation residence card, which I found many other providers could not do.

I've been a customer for years. I really like Sakura Mobile. My most recent interaction was getting their help setting up my new iphone. They were patient and knowledgeable.
