I bought Vectone mobile sim in £1 on which I got £10 as credit to call or text within UK. It was great £1=£10 credit totally free & free SIM.
Then they gave me another offer £1 for 1 GB DATA PACK which was the cheapest mobile data pack in UK. I used this offer for around 3 months.
Now they have taken away the offer & 1GB DATA PACK cost is increased to £5. Now searching some other cheap data packs lets see.
