Overall good
Purchasing and activation experience were very simple, was able to quickly purchase esim on airport wifi and activate before leaving customs! However while travelling, the service dropped randomly. I had to uninstall and reinstall the esim to get data service back. Not sure what the cause of this was but it worked after reinstallation.

Top eSIM Provider
Good experience signing up, price is good and I also received an honest discount from a code from YouTube creator. Sometimes I’ve used codes for other products saying X% off and it’s just pennies and discount not as stated. Service is excellent and can check usage on app anytime. I would recommend Ubigi as a top eSIM provider.
