Rain VoLTE pitfalls

Rain Ticket #***6 was logged 18/12/2024 due to the non response to ticket #***6 logged 18/12/2024....and still no response. The one Rain mobile sim card does not work on an LG device. The RainCall app also does not work, APN is Rain, and rendering this device with limited use, cannot make calls, and receiving calls is a hit and miss. I am still awaiting Rain's follow thru on the above tickets. It seems that technical challenging requests are being sidestepped and easy requests are processed.

For those who are showing interest in using the Rain mobile cards need to consider the following before hindsight 20/20 kicks in. 1)Will your device work VoLTE. Although many newer handsets spec VoLTE, the Rain sim is a hit and miss on various handsets I tested. Low to mid range Chinese devices (~R3000 - ~R9000) did not work. Only a few high end Chinese devices (> ~R9000) worked. A Korean device at > ~R9000 was found compliant. 2) Are you willing / do you have the finances to buy a new device when you determine the device is not VoLTE compatible or the RainCall app is not functional. 3) Test the Rain sim card first before doing any porting of your number. After porting your number the period before porting your number to another network is 90 days. 4) Do you have the time on hand and are willing to go and test the Rain sim card on available demo models? 5) How will you manage voice calls should you experience the limitations in (2). Does your current device have a dual sim card to have an interim fallback plan for voice. 6) If you have only a single sim card device, you will have to make sacrifices and efforts to get connected on all the mobile communication avenues for day-to-day business and notify all entities of your number change, whilst you wait the 90 day period to port your number to another sim card, and then revert back to your number. 7) Will you have VoLTE or 4G coverage should you have to travel and being connected on your mobile device is of importance.
