Can I recharge with another phone number?

Yes, but you need to call Lumos to temporarily change your number to the one you wish to use before you can do that

Is there penalty if you default payment on mtn lumous solar energy and how much is penalty per month?

Yes there is, before buying read there terms and conditions

Inform Lumos or MTN if you got it from MTN, they will help you.

Call MTN customer care on 180 and explain to them, they will guide you on what to do.

After paying for 4years what's next?

It becomes yours and no subscription required again

I've paid for 992point 30days plan out of 1800 points but the remaining points 808. How much will it cost to pay the balance? The original total cost was N220,000:00 but it seems the cost of the remaining years is incredibly increasing more than the agreement. I'll be glad if you enlighten me on this. Thanks.

I requested MTN to tell me the exact amount to be paid to be free during my time with them but they refused so if u want to complete the payment, u can start by paying for yearly plan which is 365 days and if you pay it 2 times then it will be 730 days

730-808
= 78

You will have 78 days remaining, you can now proceed with 60 days subscription which will be:

78-60
= 18

Pay for 10 days, then 5 days and use their daily plans to complete the payment

That was what I did since they refused to tell me the exact amount I need to pay to be free from them.

Please can I change my mtn solar with mtn prime I mean to upgrade
