I've got two phones with 3 Mobile, which was taken over by Vodafone. They want me to migrate across to Vodafone because they are progressively shutting down the 3 Network. Both phones eligible for upgrade, and, in fact, I can get two new phones for less per month than what I am paying now. But ... I was with Vodafone many years ago and their coverage was woeful. They keep telling me they're investing millions in new towers and infrastructure, and I've no reason to doubt that. But seriously, right at this moment, can you tell me that it's worth making the jump, or should I go with some other option?
