I have a pocket wifi with sim which I used serval months ago, when I turn the device it displays a message 'limited service' I believe this is because the sim card has been deactivated due to lack of use. What is the best to get the pocket wifi working again:
Reactivate the sim?
Buy a new sim?
any advice greatly appreciated.
PS. as this is a mobile broadband device it is not important to retain the sim phone number.
