The phone number prefix '0701' and the bank name 'Gtbank' strongly indicate Nigeria. The name and MTN network further support this.

Kaduna is chosen as a representative city in northern Nigeria where the name Umar Abubakar is common. Exact street or landmark is not visible, so city-level precision is given.

Lagos is Nigeria's largest city and a major financial hub where GTBank and MTN operate extensively. The phone number and bank details fit the Nigerian context, so Lagos is a plausible alternative location.

Abuja is the capital city of Nigeria and hosts many financial institutions including GTBank. The phone number and name suggest northern Nigeria, making Abuja a reasonable alternative guess.
