OK So I'm currently without a proper phone over the weekend as my number port backwards and forwards away from o2 is in a bit of a mess.
So basically I was stuck with silly o2's payg bolt ons which seem to take 48hrs to work - meaning I was paying 10p a text. Owch!
Anyway remembered I got a load of orange PAYG sims in a drawer, so quickly registered them. Rung up to register my details for my free £1 credit, and just in random chit chat mentioned I was only gonna use it for a couple of days.
Next thing the foreign sounding op put me on hold for a few mins, came back and said because I was only on Orange for a couple of days, he would give me 50 texts for free!
How random is that!
I thanked him and asked why, and he said maybe it will make me change my mind about vodafone and choose an orange sim only deal instead! (and I'm so impressed I may just do that!)
