Not being able to make or recieve calls
Just an update, the Sony Xperia 5iii is not on the list of incompatible phones, the xperia 5ii is, I have finally gone over to lebara, phone now works fine, making and receiving calls and smarty complaints was nice enough to give me a full refund for the 2 months I spent with them and supplying me with a PAC code, so would like to thank the complaints department for there help.
On another note i would like to see them put the Sony Xperia 5iii on their list of incompatible phones and advise there tech support guys on the issue so no one else has to spend ages resetting, checking and changing settings on their mobile with no gains
Unfortunately, if your phone isn't compatible with Smarty's VoLTE - and it sounds like it isn't - the only two options are to go to a network where it is supported, or change to a handset which is supported by Smarty. There is no fix, as such.
As I understand it, mobile device manufacturers and mobile network equipment manufacturers all implement VoLTE in slightly different ways. Carriers like Smarty need to supply the specific settings for their VoLTE to the device manufacturers to include in the firmware on their devices, who in some cases actually depend on the chip manufacturers to incorporate the VoLTE settings. Unfortunately, Smarty can't control when these updated settings will get pushed out to the devices by the device or chip manufacturers - if they ever get pushed out at all.
So why can't SMARTY just make their system compatible with the others?
