Sorry for the long ramble but I am looking for advice: My meter has been playing up for sometime by intermittently refusing to waken up when either switched on or a test strip inserted usually when I'm out and about! My DSN gave me a replacement which does exactly the same thing. I can solve the problem by taking the batteries out, putting them back in different order and wiggling them about. This is ridiculous so eventually I rang the Roche helpline where a helpful techie verbally gives me a very long list of reboot instructions and tells me I should be carrying a back-up meter with me at all times anyway. Now my DSN tells me the Expert meter is discontinued and the next time I see her we'll talk about the new version which will need to talk to my phone. This is a concern for me as I'm a teensy bit of a technophobe so thoughts and advice would be much appreciated, in particular if there's any particular smart phone which would be recommended as I suspect I will need a new one of these also.
