    @O2 What’s with the 4G Issues at the moment? As soon as leave the house and go onto the mobile network nothing works. I can have full 4G and full signal but nothing is working and it’s starting to annoy me. I can’t use something I’m paying for.

  • aaronjay_b Aaron (@aaronjay_b) reported

    @O2 trying to pay off my device plan on the app and it’s not allowing me so I’ve called 202 and I’ve been on hold for 20 minutes. Do they close at 5 if so I’ll hang up now!

    Has the @O2 signal completely stopped in Durham?! Getting no signal at all

  • sallyshalam Sally Shalam (@sallyshalam) reported

    @O2 Happy to. Appears I am not alone in discovering one’s tariff does not include emojis (54p) or more than 160 chars. I don’t need either but if your service dept spend their days explaining this to customers, clearly we are not alerted sufficiently at point of sale.
