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

Had the same problem with my Xiaomi. The problem is nothing to do with whether Smarty has listed a particular model or not as some users seem to think. Provided that the phone is voLTE compatible it should work as it did on my Xiaomi for 5 years. Then it stopped making or receiving calls, but texts could be sent or received and data worked fine. Tried the Smarty SIM in a friend's Samsung and all worked fine. Thinking that there was something wrong with my Xiaomi, wasted time doing a complete factory reset but to no avail. Then wasted money buying a new phone. The Smarty SIM worked fine on the new Motorola for a few days, then stopped making or receiving calls but texts/data ok just like on the old Xiaomi. Conclusion, the fault is in the SIM chip and it appears to be an intermittent problem. I don't know where Smarty buy their SIMs from but there are several manufacturers and obviously the one that made mine needs to be held to account.
Will obviously ask for a replacement SIM from Smarty but in case they disconnect me while waiting for a new SIM, I've signed up to both Asda and Lebara. Their SIMs work fine on both the old Xiaomi and new Motorola but then again, they too may fail after 5 years.
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.
