I bought this phone in Malaysia @ Lowyat PLaza.. Paid RM1099.. The Hyundai Multicav Q5L+ has good features & worked Ok in MY using the MY SIMs but when I moved to India (Chennai) it stopped working. When I put my India SIM (Vodafone) and the MY SIM - Tunetalk (it's a dual SIM phone) neither of the network signals seems to pick up. Note, the phone does display that its a Vodafone SIM, Tunetalk SIM etc. but no signal and there is a "cross" displayed next to the signal bar. I tried selecting the network manually but that didn't help. When I contacted the MY vendor (who sold me the phone) he said something about the IMEI range registered on the phone being different than the one in India and hence the phone needs to be patched. Apparently it can be done by some of the service center shops locally. When I went to a few of them, they took a look and couldn't figure out how to fix it for this brand of phone. Note, both the SIMs (incld the MY one which is on roaming) work perfectly well with my old phone which I had purchased in India. So nothing wrong with the SIM cards or the networks in general but something to do with this phone. Any help will be appreciated.
