I have an old laptop with me that I am not using and I have thought of running node before but that was not possible because I do not use solar and that I do not have solar but run on generator when there is not light but mostly at night.
Another problem is that we do not have unlimited data in Nigeria. The only unlimited data in Nigeria is Starlink but it requires ₦590000 to buy the kit while the standard (lowest) subscription is ₦57000 per month.
The cheapest subscription in Nigeria is to go for yearly plan and not *121# which can double the data for you for monthly subscription but still costly than yearly subscription. Annual subscription is still cheaper. Also the *121# offer is removed at anytime by MTN which makes it not reliable.
As at 2 years ago, you will need like 380 gigabyte to download the full bitcoin blockchain. I guess it will be more than 400 gigabyte by now. Also after you finish downloading it, you will still need data to receive information from other nodes and also data needed to route the information to other nodes which will consume significant amount of data in gigabyte daily.
What I saw you did with that image, I have done it before like 3 or 4 years ago and it was not hard at all when I downloaded Bitcoin Core from the official website, but I stop it when I know I can not be able to continue.
Another data provider problem is poor data network is now very common but 4G users are the ones complaining where 5G is available. I have 5G router and 5G phone which the network is very good but my 4G phone is very frustrating, unlike before. I hope they will find something to do about it as their mast are getting older.
