Forgive what must seem like very basic ignorance.
A brief explanation. I rarely use my own private Mobile.
Work from home (landline) and Employers supply their own mobile for me, which I use freely when travelling around.
Over Christmas, I won't have the Work mobile, so have decided to update my old private mobile.
I have a Siemens PAYG mobile on Vodafone with a about £40 credit left.
It's about 5 years old
I would like to upgrade this to another more modern PAYG mobile, however I would really like to keep the same Mobile Phone Number and probably stay with Vodafone to keep the credit (if that's how it works).
What would be the best way to go about this, please?
Not really limited to a budget, but it won't be used much and value for money would help.
Any help appreciated. Thanks
