What building TeloSim taught me before our Product Hunt launch 🌍

Hey everyone 👋

As we get closer to TeloSim’s Product Hunt launch (in just a few hours 😬), I wanted to pause for a moment - not to promote, but to reflect.

It’s been 4 months since TeloSim went live, and honestly, the journey so far has been equal parts humbling and exciting.
I built this because every trip abroad reminded me how broken mobile connectivity still is. The silence when you land, the overpriced roaming, the kiosk hunt… we’ve all been there.

Building TeloSim, a platform that gives instant eSIMs for data, calls, and texts in 150+ countries with NO KYC needed - forced me to think differently about user trust, tech simplicity, and communication. It sounds simple, but making something “just work” globally takes a ton of small, invisible effort.

Now, a few hours before our first Product Hunt launch, I mostly feel gratitude. For early users who believed in a product that didn’t yet exist, and for other makers who taught me what real feedback looks like.

Here’s something I’m curious about from others here:
👉 What’s the biggest lesson you learned before your launch — something that changed how you approached it?

I’ll be around replying all night while we wait for the clock to hit launch time.
Big day ahead - thanks already for being part of it. 🙏
