The first experience with Bluefirewireless in India is:
In four days the SIM card did not log onto any local network. Lucky I had my local Airtel prepaid and could do my calls as usual.
I requested support through Email and received an answer within 6 hours. Very positive impression. After replying with a contact telephone number I waited for a call through the service. Until today nobody called me back...
Next week I will stay three days in Barcelone area and in the second week of February I will test the service in Saudi Arabia and United Arab Emirates. Let's see...
