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
This is highly unlikely to be a SIM issue as texts and data are working. Your statement that any phone that supports VoLTE should work with Smarty is incorrect.
Different mobile networks and different phone manufacturers all implement VoLTE in slightly different ways, and a phone with VoLTE will only work with Smarty if Smarty's specific VoLTE configuration has been included in the firmware of that phone (or if Three's VoLTE configuration has been included, and the phone is smart enough to know to use that). That's why Smarty have their device list - funnily enough, being a mobile network, they understand this situation a little better than you do.
If you're saying your Xiaomi worked fine on Smarty for 5 years, that will be because it will have been dropping down to 3G whenever you made or received a call in the past, due to it not being compatible with Smarty's VoLTE. It now can't do that any more because most of Smarty's 3G has been turned off, hence calls are no longer working for you.
Not really helpful though? My iPhone is fully compatible and the Smarty Sim allows internet connectivity but excludes many telephone calls both receiving and calling out - which is the purpose of having a telephone believe. Once I find a reliable network provider I’m going to leave Smarty. It’s not worth the stress. It worked great for years but the time has come to dump Smarty unless they improve their game.
ThomasB_1004178 Have you checked that it is set to 4G/5G?
I am assuming here that it’s not before iPhone 6 as that won’t work.
