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.

USA travel experiences with an eSIM: what users say
Travellers report time and again on fast activation, a stable connection and convenient use – both in urban hubs like Miami and New York and in more rural areas.
Even the tech-averse appreciate the straightforward handling. For many, a 3 GB package is enough for a week – that usually covers streaming and navigation well.
Anyone planning group trips or national parks sometimes even uses two eSIMs on different networks to have reception as widely as possible – you can consider this if needed.
Should problems arise after all (for example if a QR code is lost or the device does not support eSIM), BuddySIM's English-language customer support is available and can help quickly. With an eSIM for the USA you can handle formalities like activation paperlessly and conveniently from home – simple and fast.
How to find the optimal USA eSIM for your trip
Ask yourself the following questions before deciding on a USA eSIM:
- How long are you on site?
- Do you mainly need data for social media and map apps – or also for streaming and working?
- Are you travelling around with family or several devices?
- Should your plan also be valid in Canada?
- Is a data plan enough, since you make calls via WhatsApp anyway?
With BuddySIM you have flexible options: choose from 1 to 50 GB (7–30 days), a hotspot function is included, and you can activate the eSIM in advance from home. That gives you planning security – with no long contract terms. Also practical for trips with several stops or border crossings into Canada.
