Phone stopped making and receiving calls
it worked well on another phone. it is good to confirm that i have exhausted possible cures (except a major reset of phone). i have tried the web chat bot a few times, but personally i think it's a waste of time. ai can't replace real humans yet! thanks a lot indeed!
Hi QinYang_1314494,
Sorry to hear about your problem.
Does you phone support 4G calling, and is it enabled in your handset settings?
If you have two SIM slots, you can try putting the SIM in the other slot. Sometimes VOLTE doesn't work if there isn't a SIM in Slot 1.
You can check if your phone is compatible with 4G-VOLTE here.
Thanks,
YulianK
QinYang_1314494 Not sure if this is helpful........
https://help.kogan.com/s/article/Doesthisphoneworkwithmyprovider2 and also https://help.smarty.co.uk/en/articles/4670061-what-bandwidth-and-spectrum-is-available-on-smarty This seems to indicate that your phone should work in the mid band, but not in Smarty's low band maybe?
I also found this quote (and similar repeated often) : At a high level, low-bands have greater coverage but lower speeds, mid-bands have a balance of coverage and speed, and high-bands have higher speeds but less coverage. In addition, each band presents opportunities for a service provider to balance between frequency, coverage, quality, latency, and reliability
Is it possible that the phone does not like the UK frequency bands? I'm assuming that yours is Australian here, so hope I'm not wasting your time.
please read my three replies in reversed order
also, under 'sim cards', both 'sim slot 1: smarty' and 'mobile data: smarty' are in black and i can choose to switch them off; but other items are all in grey: 'calls: smarty', 'sms messages: smarty', 'allow to access mobile network during calling (switched off)'. why are they in grey? are they set as default?
many thanks for helping me pursue this issue. i checked the settings on my phone (a cheap yet robust kogan model of agora xi), its 'mobile network' indicates smarty; its 'preferred network type' shows 4g; and its APN shows: 3 (mob.asm.net). its 'sim cards' shows 'sim slot 1: smarty' (followed by my phone number); 'sim slot 2: sim empty'; and 'mobile data: smarty' (which is correct, since smarty data works well on my phone). the mistery continues ...
