ZTE with Smarty SIM not connecting to internet

[SiwanJo_2699145]

Hello.

I've got a ZTE 5G MU5120 travel router which I want to use in our van. I bought a 2GB plan and everything was fine until Saturday night but on Sunday we'd used up this data allocation. So I've upgraded the plan, but, as that doesn't start till June, I've also bought a £10 add on to bide me over. However this doesn't seem to work as, when I connect my phone or laptop to the ZTE, I get a 'Connected to device. Can't connect to internet.' message. ZTE has Wifi. Am I supposed to do something with the 'add on' to get it to work?

Thanks. Siwan

@SiwanJo_2699145  Please take a look at the Price Guide for Add Ons: https://cdn.smarty.co.uk/files/SMARTY-Price-Guide.pdf?_gl=1*1uhnyd7*_ga*NDUyNjQ2ODc1LjE3MTI1NjY2NDE....

Specifically, you need either p14 or p16 - your choice. It sounds like you have perhaps bought an Out-of-Plan add on on p15.
