Worst customer service. SIM card was not working suddenly. The customer care quoted that it was due to a 'technical issue' at their side. I had to order a new SIM card again by paying 5 EUR to retain the same number. My wife's SIM also stopped working suddenly. The customer care said that the SIM has expired !!!
