please house i would like to know if it is possible to use my glo or mtn while in london. if anyone knows,advise me on how to go about it. thank you.

is that to make and receive calls in london you mean? i dont know if it works now but that would be roaming and therefore higher. just buy a pay as you go UK sim card and give your number to people. if you are staying in the Uk for longer you may consider buying a contract phone

Simply conduct a network search with your Nigerian sim. All available networks will be listed when the search is complete. Choose any of the networks that has a roaming agreement with your sim card provider and that is it.

There is a charge to make and receive calls. So if you a Prepaid customer, make sure you load your phone with enough funds before you leave Nigeria.

Glo and MTN networks are South African network,you can use it while you are in London.But roaming charges will be applicable.Because MTN,Glo are not available in London.If you want to avoid this roaming charges you need to use pay as you go sim card from United Kingdom(UK).If it is an unlocked phone,you can use any GSM network sim card in London.But if it is a locked phone,you need to unlock it.To unlock mobile phones,you can use unlock code.Specify mobile phone brand and model.Get the unlock code from the site www.Mobile-Unlocker.com and unlock it easily.
