Last year we bought a TP-Link MiFi in Spain. The supplier was MediaMart who also sold us a Vodaphone data Sim card that never worked in spite of two returns to MediaMart. Back in the UK we bought a 3 data Sim which worked perfectly. Once we were back in France, Spain and Portugal no amount of trying would allow the MiFi to link to our phones or tablets.
After a lot of searching we found a 3 contact number. They spent a long time trying to make my wife's Ipad work but we then had to contact TP-Link for additional help including re-booting the Mi-Fi. This still left us having to phone 3 again for a final password.
I did get advice from Fun but it did not apply to our Ipad. I know some tablets and phones should work straight away but our Iphone, IPad, Surface and Lenova phone, did not.
