Unable to make calls
Hello, please help!!! I don't make calls very often so thought it was a service issue but I have good signal and 4G, and texts come through fine. Sometimes I can receive calls but I have had SMARTY since September 2025 and haven't been able to make any. I don't use whatsapp or instagram or anything on this phone, only texts and calls (well receive them as I can't make them). I also use the safari app but it's been very temperamental and I thought perhaps because I have an old phone (iPhone 5S) but surely calls would work?! And I have 4G?! When I try to call mobile or landline numbers, and even voicemail, it comes up that it is calling but then is silent with no beeps or anything and doesn't go through. I have voicemails that I can't listen to and need to ring the doctors but I can't!!! I'm paying for data and calls and texts which I haven't been able to use... please can you help fix this issue as I'm paying for a service that I am not receiving.
4g calling/volte on Smarty's blacklisted phone (Sony Xperia XZ2 Compact)
I'm usig Sony Xperia XZ2 Compact (last 5 inch android from Sony) and i think i solved (or it solved itself) the 4g-Volte problem on it. Sony XZ2 phone is on Volte support blacklist at Smarty, so 4g calling should not work, but i didnt want to give up that easy. Before and after "3g switch off" all my calls switched to 3g(H, H+) doesnt matter that internet ran on 4g. So i installed LineageOS, fully rooted the phone, and noticed that Smarty Sim doesn't get network modem configuration, in fact Smarty modem configuration folder doesn't exist at all in this phone. So by using "Root Explorer" app i had to create "S21.4" folder inside "root/vendor/modemconf/" ,then inside it create a file named "modem.conf" which contains "mcfg_sw/generic/euro/hutch/vlvw/uk/mcfg_sw.mbn" line. (Btw i recommended to take sim off or switch to airplane mode before doing this). Restarted the phone and now i can make and receive HD calls, Volte still not showing in the menus, but my calls don't drop to 3g anymore. Data, SMS also works.
Unable to make/receive calls using on a Motorola Moto E7i Power phone
Hello, I'm wondering if any of you have advise or can help me I am unable to make or receive calls on my Smarty sim in my Motorola Moto E7i Power phone. I've tried all the hacks suggested when typing this issue into Google however still unable to make calls. The mobile network state on the SIM is advised as 'Disconnected' . The mobile voice and data network types are advised as 4G I don't make or receive calls often so it hasn't been a big issue since moving to Smarty however I do need this functionality Any advice is much appreciated Thanks
