What is an eSIM?
eSIM stands for “embedded” SIM which is installed in your phone by scanning a QR code or tapping a notification. If an activation date is required the QR code / Notification is sent after activation, else 24hours after completing your documentation.
eSIM Advantages
- Easy to use: Set up your plan by scanning a simple QR code or tapping a notification.
- Save on Shipping cost: No physical delivery requirement
- Save on time: In a rush to travel? We will send eSIM QR Code via email. Scan it as per instructions and It will be ready to use upon arrival.
- Keep your original SIM: The eSIM is in addition to your original SIM which will work as usual if you need it.
eSIM Disadvantages
- Unfamiliar: Since it is a new technology expect to be learning a bit.
- eSIM Compatible Phones: eSIM will only work in eSIM compatible phones. As a general rule, iPhone 11 and Android model 2021 and higher models are compatible with eSIM.
- Single Use Only: Most eSIM codes can be used only once. Please do not delete the eSIM created on your phone, since it cannot be recreated on your phone or any other phone. However you can de-activate the eSIM when not needed from your settings.
- Transfer of eSIM: Transfering an eSIM from one phone to another is usually not possible. However some eSIMs can be transferred from one iPhone to another.

Variation: Physical, 14 Day Unlimited Data
I had puchased a 36 country Unlimited Data only physical SIM for Europe for 20 days, for our recent trip to Scandinavia in July 2026
I switched on my phone after landing in Zurich ,just to check it out, though our destination was Copenhagen. the SIM worked very well, without any hitch during the rest of our trip spread over Denmark, Norway, Sweden, Finland and Estonia too.
I will highly recommend this Unlimited Data Only SIM to anyone who does not require calling facility because these days, mostly WhatsApp calls are made to any country in the world,which only requires access to data.

Thank you for your kind review and specifying the countries in which you used it.

I recently purchased the Unlimited Data only SIM valid for 20 days,on my trip to Scandinavia in July 2026. I switched on my phone,where the TSim was already loaded,after landing in Zurich,as Switzerland was also one of the countries covered. Throughout our trip the SIM worked beautifully,and there were no data drops. The speed was also very good!

I used a physical sim (received it in a day) for my trip recently. Had taken a 30 days package with some 29-30 GB with 100 minutes calling.. It worked seamlessly in Poland, Norway, Czech Republic and Germany. But totally failed in Sweden (just couldn’t latch on to any of the local networks) so neither calling or data worked. In Denmark, data is was good as absent (only edge network that hardly worked) and calling was active. So if you are planning to go to Sweden/Denmark look for alternatives as I had to separately purchase roaming for those days.
Services Tsim –
We are sorry you could not use your SIM in Sweden and Denmark. We are looking into the specifics of this case. Thank you for your balanced reply.

I am a repeat TSIM customer. I used this SIM on my recent Italy trip and it worked just fine. I was able to connect without any issues and the speed was good. What I like about TSIM is that eSIM and physical SIM are the same price so you can use it even on older or mid range phones that don’t support eSIM. Would highly recommend.

Bought the physical data SIM card. Delivery within 2 days at Bangalore. SIM worked perfectly from the time I landed in Cyprus, and later in Greece. Would suggest TSIM to look at lowering the prices if possible.
Services Tsim –
Thank you for your kind review and for mentioning the countries in which it worked. Our prices per GB have been steadily reducing and are about half of what they were 18 months ago.

Highly unreliable! I took the above 30 day 30GB esim. Worked well initial 4 days in Denamrk but when i entered Norway, it stopped working completely after 5 days and only 5 GB data use. Contacted tsim care but no timeline or resolution. I had to use My Indian service provider with very high roaming charges. Please refund my money and stop selling such Unreliable products as they can affect TSim reputation

We are sorry the SIM did not work for you. We have processed a refund and hope you will give us the opportunity to serve you again.

I bought this SIM for my trip to Switzerland and Italy in Apr 2025. It worked perfectly, got activated within a few minutes after landing in Switzerland, and then worked non-stop through our 12 day trip in these 2 countries. It connected on 4G+ instead of 5G a lot of the time, but that could well be due to limited 5G band support on my low end Motorola India mobile phone. Would definitely recommend this SIM for anyone looking for data in the EU – WhatsApp calling including Video worked perfectly across remote and metropolitan locations.
