5/5

I tried Redteago esim plan on my trip to Seoul. The convenience of the esim plan was fantastic. I simply activated the esim on my device with a few simple steps which saved me from the stress of finding a local provider and allowed me to stay connected immediately upon arrival in South Korea. Throughout the trip I had seamless connectivity. Purchasing an esim is the ultimate enabler for a hassle-free mobile experience when travelling.
