To become a real expatriate, you should have your English number! To talk with other people, to contact your work and to find room in the city.
I recommend to just buy a sim card if you spend only few months in the country.
Mainly, the sim card would cost between £5 and £10. Depend on the operator, you could buy the sim card on internet or on the shop.
- GiffGaff : It’s the operator that I have chosen. In only few day I have received my sim card and I pay only £10 by month (for 500 UK minutes + unlimited UK texts + 1 GB UK data + free to giffgaff numbers)
- Freedom Pop
Be careful to have an unlock mobile before leaving !
