I have a Nokia 6303i classic with an old O2 sim in it and I want to change to Vodafone as O2 has very poor coverage here (read none at all in our village) whereas Vodafone has great coverage. It's not a matter of the card size it's the contacts on the sim have changed on modern sims. Is it possible to change or buy an old working one. I just love the software on this phone and it works much better than Nokia's new phones. I bought a new 105 2023 version and it is so awkward to use and lacks all the old options that makes the 6303i so great. Also the processor is so much faster it's unbelievable. I bought the O2 sim when I lived in London and it was OK there. Since then I've retired and moved to East Sussex to a part that has no 02 reception.
All the best
Roy
