EtravelSIM provides a seafarer eSIM that covers Niger along with 181 other countries. The plan includes 10 GB of data, a validity of 30 days, and costs $29.99 USD. The phone number supplied uses the dialing code +33 (France), so it is a foreign number rather than a local Nigerien line.
The eSIM allows inbound and outbound voice calls as well as inbound and outbound SMS. Because the number is not a Niger local number, callers will need to use the +33 prefix and the receiver must be able to accept international numbers. Travelers interested in this type of service should verify the exact dialing method and any potential roaming restrictions directly with EtravelSIM.
