I changed my old £75 a month tarriff + unlimited text bolt on to their new " cheaper" £60 a month tarriff unlimited everything. So I cancelled my text bolt on easy right makes sense er NO 02 the thieving rats have changed things. So yes I have unlimited texts but instead of a mms picture message costing 4 of your allowance it is now costing 20p each. I am busy sending loads of these mms and after a very long call to Canada decide to check my " recent charges" I couldn't understand what was going on until I read their new tarriff carefully But yes. I saved 15 a month. Lost my bolt on which I can't get back and am now paying more than 15 a month in mms. Thanks for the transparency o2. Just thought I would warn.
