I once bought a 50GB travel SIM, only to find out after arriving overseas that the seller had quietly limited my speed to 5Mbps.
My family was sharing my hotspot. The slow connection affected our plans. Even checking train-ticket details and opening a QR code became a struggle. I never used more than 10GB of the data I'd bought.
The problem wasn't the unused data. It was letting my family down when we needed to get online.
That experience stayed with me. When I started Traverrsim — the business behind today's Lumoo eSIM — my first step was finding suppliers I could trust.
I wanted one rule to be clear from day one: No hidden speed limits. No surprises after landing.
Later, a customer told us the only place they could get a signal at their accommodation was the bathroom. We offered a refund or compensation. It was another reminder that travelers rely on their connection far from home.
Then I noticed something else
Travelers have enough decisions to make.
- “Is 10GB enough?”
- “Which plan should I choose?”
- “Will it work for my trip?”
That's why we're bringing AI into Lumoo: to help travelers compare less, choose with confidence and understand their data usage without needing to be tech experts.
Travel connectivity should be transparent, simple and one less thing to worry about.
That's the idea behind Lumoo eSIM.
Our promise is transparency, not a guarantee that every network runs at an unlimited speed. Applicable speed limits and fair usage terms should always be disclosed before purchase; actual coverage and performance depend on the destination and local network.
