I had taken international roaming plan of my Jio number by paying Rs.1102/- for 28 days to use my Indian number in Malaysia. But after recharge I am unable to connect network in Malaysian service provider MyMaxis or U-mobile. When I contacted Jio customer support, they did a lot of setting change like selecting 2G/3G preffered network in phone, switching off wifi calling in phone, manually selecting available network, switching off international roaming through SIM tool kit etc. But all these setting had not resulted any positive and I am still unable to connect network continuously. Sometimes it connect but within a few minutes it disconnect. I presume possible reason for such a problem originates from the fact that in Malaysia 3G network is no longer available in MyMaxis network. The 2G MyMaxis network is running but with poor network strength. I suppose due to network strength such a disconnection is happening. Jio should know this reason and should not offer international roaming in 2G/3G networks to cheat the customers.
Airtel international roaming is offered in 4G network and no such problem exists for Airtel customers. I am also using their service through my another Airtel SIM.
Hope Jio will take some real action to resolve the issue. People should not buy Jio international roaming plan for Malaysia and waste money.
