AVOID at all costs!!! Please, please do not use Vodaphone. We have a business which used their sim card for an internet router. Vodaphone deliberately moved the refresh date for the data twice in the last year, the first time without our knowledge or confirmation (we fought this charge and was offered a discount and won) and the second time at the most disadvantageous time for us a business but to a date which would net Vodaphone the maximum amount of extra money (just received a bill for over £700.00). Be aware they do NOT cap their data usage (no matter how many times we asked) and our Vodaphone sim card serial number would not work with their online registration system so we had to install our own software to monitor it but due to them changing the refresh dates we could not tell what we were using accurately enough to monitor it. Their customer service is atrocious with one representative saying they will phone back or email and it never happening and then when we call again, the notes from our previous conversation mysteriously disappear so we have to start again. Thank you for reading this review.
