The story behind BuddySIM
BuddySIM was born during my parental leave, out of real frustration. Expensive roaming fees, stressful queues at the airport with small children and a complicated hunt for SIM cards on site? It doesn't have to be like that.
A holiday is the best time of the year and should be worry-free! That's why I founded BuddySIM, so you can focus on what matters most on holiday: relaxing and spending time with your loved ones.
