SIM and eSIM for volunteer and mission travel
Put a one-time eSIM code in the pre-departure guide, so volunteers land with data for the airport pickup. SIM packs wait at the orientation for phones without eSIM.
Short answer: Volunteers land in a new country and look for the pickup, the host family, and the group chat. The one-time code goes out with the pre-departure guide. The orientation keeps SIM packs for phones without eSIM, and a long placement gets a new eSIM for each further 30 days.

Before you choose
Short answers to the common questions. The partner agreement sets the final terms.
Who gets the code of a volunteer under 18?
A parent. The code never goes to the volunteer, and the parent installs it before the flight.
Does the plan work at the project site?
Where the local mobile networks reach the site. Check the coverage first, and keep Wi-Fi at the base for a rural site.
What about a placement of three months?
Start with a 30-day eSIM. Each further 30 days is a new eSIM, with no limit on the number.
Who sets the price?
You do. You buy at a partner price and sell it with the program, or include it in the program fee.
