First off I have set up the mifi and it works but when I put the sim back in I get missed calls and texts.
I only want to use the mifi for travelling as the battery lasts most of the day and when using on phone it lasts a hour or two before draining the battery so not good if on a train.
Can I redirect my calls at least(maybe not the texts) to my PAYG phone whilst I am travelling just in case I get an important call?
