Sending airtime to a family member in Lagos, a friend in Accra, or a colleague in Nairobi used to mean buying scratch cards or hunting for local agents. In 2025, it takes less than 60 seconds from anywhere in the world — if you use the right platform.
This guide walks you through exactly how international airtime top-up works, which operators are supported, and how to send recharge to any number without paying inflated fees.
What Is International Airtime Top-Up?
International airtime top-up (also called international recharge or cross-border recharge) lets you add calling credit to a mobile number in another country. The credit is delivered directly to the recipient's SIM — they don't need to do anything or have a smartphone.
Who uses it? Diaspora communities sending airtime home, businesses topping up staff phones abroad, travellers keeping a backup number topped up, and developers testing VTU flows.
How It Works on Numproxy
Numproxy uses the Reloadly network to connect to 800+ operators across 190+ countries. When you submit a top-up, Numproxy sends the request to Reloadly's API, which forwards it to the local operator in real-time. The entire process typically completes in under 30 seconds.

Pro Tips for the Best Rates
A few strategies to maximise the value of every top-up:
Fund your wallet in advance. Numproxy wallet top-ups lock in the exchange rate at the time of funding. If you know you'll send regularly, topping up during a favourable rate window saves money.
Check promotional bundles. Many operators offer bonus airtime during certain hours or days. Numproxy shows these promotions on the airtime screen when available.
Use the API for bulk sends. If you send airtime to multiple numbers (e.g. for staff or customers), Numproxy's developer API lets you automate this from your own system.
Tip: Top-ups to Nigerian numbers work best when sent between 6 AM – 10 PM WAT. Deliveries outside those hours may take up to 2 minutes due to operator processing windows.
