New SIM problem ?
Activated my new Smarty SIM yesterday and I notice that the mobile number in the Dashboard is not the same as I requested (i.e. I sent a PAC code to Smarty with the details). However even though the number displayed is not mine all my old services seem (?) to be working. When my wife calls my new Smarty number to test it out there is no connection but my old number (from vodafone) still works. This is not so much a complaint as a “what’s going on” question ??Anyone else not registering on network in Falmouth?
For the past two days my phone is not registering my sim card onto the network in Falmouth? Service status just keeps saying there is a signifigant issue in the area and will be fixed as soon as possible! Not exactly the reliable service I was expecting and the info is vague. If anyone has any idea what the issue is and a ETA on a fix I would be most grateful. Oddly I get full bar signal.....so it is not a signal issue.....and looking at the data returned from the handshake it seems my Smarty Sim is failing authorisation? Thankfully I have access to wifi calling at home, however I would like to know what the issue is and when it will be resolved by.
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.
