Not reliable enough for me
I brought a sum for tunisia and installed it a few days before. Unlike the sims I have used before it activated immediately while still at home despite not being switched on and started counting down. Customer service were very good and refunded me. I purchased again on the day of travel and activated on landing in Tunisia. This was a bit of a pain as I needed WiFi to activate it which kind of defeated the object of an esim! Whilst there is was very intermittent. When my phone connected to free WiFi and then left the area I had to restart my phone every single time just to get the esim working. This was annoying and time consuming and something that you just shouldn't have to do. As a solo female traveller I absolutely depend on esims for safety. As good as the customer service were via what's app etc, I wouldn't use this brand again or recommend, simply because I've never experienced any issues at all with previous providers and connections.
