I have just signed up to Vodafone 100GB for my mobile for £20 a month but my contract with o2 has 2 months to go so intend to use the new sim in my mifi until then as noticed people had posted it was possible. Was intending to get a 50GB data only sim on 30day contract for £50 a month until I read I could use mobile sim in a mifi, saving me £10 a month. Can someone let me know that if I should put the sim in my phone to register for roaming before I cross the water. Have tried it in the mifi and seems to work ok n the U.K. Was going to register on Vodafone web site but they would send me a security code to my mobile which I wouldn't receive as sim not in phone. Looking forward to clarification from knowledgeable users.
Vodaphone sent me a text message to my Mifi device which has the ability read them.
