The BelZoSIM sims will work in nearly all mobile phones provided they are UNLOCKED.
To find out whether your phone is unlocked, insert a SIM card from a different network into your phone. If it operates normally, it is unlocked. If not, you can ask your operator for an 'unlock code' which it is obliged to give you, though conditions and charges may apply. Alternatively you can unlock it yourself by taking your phone to an independent phone shop or by trying one of the independent unlocking websites.
