Airtel is Tanzania's third largest mobile connection service provider in terms of the number of subscribers. The market share is about 27%. GSM coverage of this operator is slightly worse than that of its competitors Vodacom and Tigo, but the tariffs for services are lower. Buying Airtel's SIM cards can be a profitable investment in your VoIP termination business, provided that you choose the most appropriate tariff plan.
Airtel's prepaid line starting plans are sold all throughout the country, both in the operator’s stores and in street kiosks. The cost of one SIM card is minimal: $0.44 to $0.87. But Tanzania's law requires you to register the cards, so you better make a deal with someone to supply a large number of starting plans registered to third parties. In this case, SIM-cards are likely to cost you more.
There are several package offers for prepaid line subscribers. Let's discuss the Yatosha Mitandao Yote line, which is best suited for termination. It is available in three versions - Daily (packages are valid for 1 day), Weekly (packages are valid for 7 days), Monthly (packages are valid for 30 days). The most successful, in terms of termination, is Weekly. This range includes 4 packages:
- 35 min. Price - $0.65.
- 70 min. Price - $1.09.
- 250 min. Price — $2.18.
- 525 min. Price — $4.35.
Yatosha Mitandao Yote Weekly 250 min — is the best solution for GoIP GSM gateway operation. With this plan, the cost per minute will be about $0.008. Terminating 250 minutes per day, you can receive income of $500 and more from each gateway port (taking into account the cost of buying SIM cards).
