M-KOPA provides phones on credit.In case you fail to pay for the phone,the company will lock it and you won’t use the phone until you resume repaying the loan.
Here is the explanation from M-KOPA:
“If You fail to fulfil your contractual obligations including keeping current on your Credit Payments, M-KOPA may deactivate your Product (including by exercising a seller’s lien as applicable under this credit sale arrangement) until you become current again in your Credit Payments. This could require the payment of more than one Credit Payment in order to unblock your Account.
If you fail to keep current on the Credit Payments for the Product, your credit history may be reported to a credit reference bureau and may not be eligible for Additional Products and services from M-KOPA”
Make sure you pay for the phone you are using.
