Sudden "Not Registered On Network" (after 1.5 years) - but only with SMARTY SIMs
Summary - after 1.5 years, "Not Registered On Network" situation with a particular phone and ANY SMARTY SIMs (but Vodafone SIM works perfectly). Phone: Samsung S22 Ultra 5G, owned and used it for the last 2.5 years SIM: SMARTY - used for the last 1.5 years (we have 3 SMARTY sims in the household) On Friday, the phone suddenly started presenting "Not Registered On Network" message (and hence unable to make/receive calls/SMS/mobile network. The phone shows as connected to network (4 bars) and allows me to make emergency calls. SIM is recognised - it has its details shown. The same SIM works in other phones. Other SMARTY SIMs are NO LONGER working on this phone. However, my company SIM (vodafone) DOES work in this phone. IMEI check shows as CLEAN. Eg the problem is the combination of THIS particular phone and SMARTY SIM. All the usual troubleshooting (restarts, cleanup, etc) to no avail. Talked to SMARTY tech support without success - basically "your account is current, your SIM works in other phones, so not our problem". Talked to Samsung tech support - "phone is fine, SIM is fine, your network operator refuses to register it on the network for some reason - talk to them" Tried to talk to Three, but since I am not a direct customer of them - they are not interested. Could SMARTY - which presumably has better relationship with Three, help in some way?
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.
ACCESS POINT NAMES - worth tweaking mine for some improvements? (Samsung S23)
Hi. Over the last couple of days, mobile data signal is flickering to none existence, and signal is very poor. I rely completely on using mobile data as I have no WiFi at home. All was fine until I did a Samsung update on Sunday and now the phone is behaving like it's on 2g mostly, or 3g at the very best. I'm stabbing in the dark here, as the update can't be rolled back, but I wondered if editing phone access point names could help? I can see that Smarty's recommended settings are these: Android General APN settings (Android): Name: 3 APN: mob.asm.net User name: [leave this field blank] Password: [leave this field blank] MMSC: http://mms.um.three.co.uk:10021/mmsc MMS proxy: mms.three.co.uk MMS port: 8799 APN type: [leave this field blank] My current settings are the same except for: Name: Smarty internet APN type: default.supl.mms.xcap Plus I have a whole host of others in the settings list that can be tweaked, but Smarty doesn't state them. I've done the usual.. restarted phone / switched in and out of flight mode / and wiped the cache partition after the update. Any thoughts on how improve things even just a little somehow please? Thank you
Joining up with the Vodafone network
I recently read that the Smarty/Three network will join up with the Vodafone network and switch between the two depending on which signal is stronger. This is great news as I've had bad reception in my area. After doing some research on https://bidb.uk/ it shows that the Vodafone network is the best in my area and covers most places I go to such as work. Will we get any messages when this will done in my area?
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
