I have an old Three 4G mobile dongle. Its a Huawei, came with data which has long since been used or expired.
As proof of concept, can I take my EE SIM from my iPhone and put it into the Huawei? Three used to boast about their phones being unlocked but I don't know about dongles.
Would I need to change setting in the Huawei? Will EE take the hump and cut me off?
