Unlimited disconnecting all the time
I used 5 day unlimited ETravelSim on a trip to Spain. The data speed seems to be limited to 10 Mbit/s up and down. However, the data connection in the Vodafone ES network has been dropping every few minutes or changed from 4G to 3G. The connection was not really usable. I have tried a local Vodafone prepaid SIM for comparison. Rock solid connection with no interruptions, no change to 3G and speeds of 300 Mbit/s and higher with the local SIM at the same place where ETravelSIM had problems. Also more GB for the same money with the local SIM. I could not stream EU radios nor TV from the EU. The IP address that comes with the SIM seems to be from outside the EU. Also, the phone number that comes with the eSIM is one that caused high per minute charges to the callers from UK and the EU.
