Having one eSIM that works across 3 countries was very convenient. Coverage was good in Manchester and Milan.

Good so far, now I'm going to try their app
I dealt with Toosim before (got a refund on the website). Now I trust them and will try the app for the first time.
Easy to reinstall
I had to transfer my eSIM to a new phone, steps were easy, the app recognised the old installation and let me reinstall
Easy setup, reliable in Europe, helpful support
First, the guide and installation are super easy. Second, in Central Europe (Germany, Austria, Switzerland) it worked well over 4 weeks whenever there was a network. Third, I didn't get an invoice, but chat support was super easy too. Will use TooSIM where my mobile provider has nothing to offer.
Quick service & very professional
Quick service & very professional. I couldn't download TooSIM app after buying an eSIM. Support quickly found a solution and sent clear instructions. They gave me a QR code and I installed the profile on my Samsung. Thank you!
Simple to use
Easy to buy and install. Price was higher for Asia than some others, but I chose Toosim for their reliability. Haven't arrived yet, don't know their performance in-country, but I'm looking forward nonetheless!
responsible and attentive customer support
customer support actually explained the issue in plain language instead of sending a copy paste script. it's like i was talking to a human who knew what they were doing.
Human support that actually reads messages
I had a weird question about using the app on a google pixel 6. I sent a message through the support section and got a reply that wasnt a copy past FAQ!!! They actually addressed my specific phone model and told me exactly which settings to check. Rare to find support that listens instead of sending a generic link
Convenient app with simple step by step guides
I'm usually the tech support for my parents. I installed Toosim on my dad's phone before he went to Greece. The app walks you through every single step with pictures. He called me once, just to say it was already working. The interface is clean and not cluttered with ads or confusing buttons. Could not be simpler
Super responsive support
I couldnt figure out why my esim wasnt activating in Auckland and texted to support in whatsapp. I expected to wait 30 minutes, but someone replied in under 10 seconds!! They walked me through resetting my network settings step by step. It worked perfectly. You dont realize how good customer service is until something goes wrong, and they nailed it
Support fixed my purchase mistake in 5 minutes
I bought the wrong region pack by accident (chose Spain instead of Portugal right before a flight). I panicked and emailed their support. They got back to me 5 minutes later, refunded the wrong one and helped me buy the right one. Not a bot, a real person!
No hidden fees in prices
I've been burned by other eSIM apps where the price looks cheap, then you check out and there are 'taxes and fees' that add 30%. Toosim shows you the final price.
I used it in Italy for 5 days, paid $8.99 and that was it, I didn't notice a single surprise charge on my credit card. It's refreshing to see a company be straight up about cost.
Good coverage, convenient to use
Having one eSIM that works across 3 countries was very convenient. Coverage was good in Manchester and Milan.
High performance in cities
Used it all over Toronto and Mexico City with consistent performance. For a major destination it worked exactly as expected
Easy to keep track on the remaining data
The app made it easy to monitor data usage and top up without troubles. I checked it daily and never ran out

Straightforward app
The checkout process was straightforward and fast. And there was no upsells or anything!
Good price
The price was better than what I saw at airport kiosks, and I didn't waste time standing in line. Good value overall.
Clear and simple app
I was nervous because it was my first eSIM ever, but the instructions were simple and nothing broke. I'd recommend this to anyone new to eSIMs.
Instant signal
The moment I landed at Narita, I turned on the eSIM and had signal before the train ticket machines. Used it the whole way into Shinjuku with zero delay. This alone made the purchase worth it.
Great support speed
I messaged live chat and got a response in under a minute. A real person walked me through one setting and quickly fixed it. Support speed was better than most airlines.
Speeds in central Paris were…
Speeds in central Paris were consistently fast. I uploaded videos and streamed music without buffering. For a city only trip, the performance was great. The connection stayed stable across cities. I didn’t notice random drops like I’ve had with other providers.
