eSimFLAG Reviews 

Funcionó perfectamente en Brasil y Argentina. Totalmente fiable. Contratada en oferta como cliente de O2.

I will use this service every time I go abroad the service is great.

Reception and connection speed was poor in most places , Egyptians don’t have a problem with connectivity .

The connection was almost always LTE. Low speed. I regret contracting the service. The mobiles around me where 5G always. I reboot my phone. Reconnect. Change the area. Geografic position. Nothing worked

Very reliable and fast service. Used whilst on vacation in Turkey recently

I love it ! It was easy to install and to use.

The first few hours after arrival in Canada I could not get it to work - only after a lot of trying different settings it finally started working. Can’t say exactly what the problem was.
Then once working it was great, smooth internet access without any problems for any application. So good product, could be made even more idiot proof for people like me (even if I consider myself reasonably tech savvy).

I got access to this via Santander select and was super happy. Worked really well, I would used them again

2 Meses en EEUU 🇺🇸 entre New York y un pueblo al norte de Michigan y fué fenomenal, internet ilimitado y con iPhone los imensajes llegan.

Esimflag is absolutely a fraud, it is not unlimited data as claimed by the company. I bought a 5 day unlimited data for 16.25 Euro while on vacation in Italy and can't use it for completely one day . Why say unlimited when it is a hidden limited data , you won't even know how many gigabyte them are selling to you . It is a scam , never buy on hope of unlimited data. Find other sources if you may need internet for streaming unless your requirements are mainly for reading messages and chats. Be warned. Most of these firms are criminals. Crimes are not only for individuals, Firms and companies do commit crimes , stealing from unsuspecting individuals . The governments and regulatory institutions must be made aware of such crime , if we hope for transparency and reduction of crime in Europe. If you see some reviews which sounds positive, be aware that some paid for it or they may be bots working for the criminals. I bought it based on their 4star reviews ,while after experiencing their scam , I wouldn't give them a genuine 1 star rating.

They advertise it as unlimited. In reality, on the very first day of my trip, after using 5 GB my speed was throttled to 200 kbps. There is no way to find the terms or the exact data threshold, it is written nowhere, and there are no clear usage conditions at all. Essentially this is disguised false advertising: yes, the data is "unlimited", just at a speed where even Wikipedia won't load. Enjoy.

Speed of turtle may say unlimited but no way my friends choice was hollafly meningitis esimflag he watched 20 movies in 14 days im on my first one

No good signal / service in Turkey and no way to contact customer service on weekends, more than 2 hours waiting via WhatsApp, but if you don’t answer in 10 minutes (with no signal…), they close the conversation.

Don’t recommend to buy this company for using in Europe … they will charge you every individual country eSIM … so when you buy the eSIM from them , check it is covered the whole Europe or not , otherwise every country eSIM you need to buy .

Bad, i do not recommend. Data shuts off, only got used like 3GB network.

Horrible company, got blocked by them on WhatsApp when trying to resolve my data issue. No where states a data cap and when I asked about it they said there’s isn’t a limit so there is lies happening. I was using for maps and instagram at night time and by the morning nothing would load. No replies no communication when asking how to make a complaint. Worst experience ever do not recommend please but elsewhere!!

I had some connection problems since the first day. The eSIM didn’t work and I contacted the assistance but I’ve never had answer to my messages!

I was given the wrong instructions regarding setting it up, so I ended up paying for both the e-SIM AND extra data

Stopped working halfway the paid period. Was fine before. The final survey arrived in Spanish for no reason
