Buying data add on before data plan runs out without losing service (while roaming)
With a new Smarty account, I purchased a 2 GB data only SIM for £5. Worked fine in the UK then I travelled to France, where it continued to work great. When the 2 GB was down just below 1 GB, I purchased a 1GB add-on for £1. I did this while in France. There was a bit of delay before the add-on showed up (maybe an hour) but the service continued fine. The next day my original 2GB data ran out and showed zero in the dashboard. The add-on showed 1 GB as expected. However, the service stopped. The only site I could get to was smarty.co.uk. A few more hours went by and the service started working again on its own. I tried explaining this to the Smarty help chat (with a person). They said it should seamlessly change from the data plan to the add-on without any interruption. As I will need to do this again next time I travel, I was wondering if anyone has seen this problem or has any thoughts on this? Any help appreciated. Thanks John
