Bitcoin transactions require internet access, so it is not possible to use Bitcoin without internet access. However, there are some creative solutions that Africans are using to access the internet and use Bitcoin even in areas where internet access is limited. Here are a few examples:

Bitcoin via SMS: Some companies are offering Bitcoin transactions via SMS. Users can send and receive Bitcoin transactions using simple text messages, which can be sent and received via mobile phones even in areas with limited internet access.

Mesh networks: Some African communities have developed mesh networks, which are local networks that can operate without an internet connection. These networks allow users to connect to each other and share information, including Bitcoin transactions.

Satellite internet: In areas where there is no internet access, some African communities are using satellite internet services. These services provide internet access via satellite, which can be expensive but can allow for Bitcoin transactions.

Bitcoin ATMs: Some African countries have Bitcoin ATMs, which allow users to buy and sell Bitcoin without internet access. These ATMs work by connecting to the Bitcoin network via satellite or other means, allowing users to access Bitcoin even in areas without internet access.
