Singapore user here. from 2017 singapore close down 2G signal.
at that time Samsung A5 2017 have SOFTWARE UPDATE , 4G+2G become 4G+3G.
if you switch the DATA to sim 2, become 3G+4G.
this is the same thing with nokia 8110 4G
when i switch the DATA to second sim , it will become 2G+4G
i assume from hardware wise 4G+3G is possible.
will nokia give software update to support 4G+3G (or vice versa) ??
I don't understand what you mean, rtenggario.
Just because Singapore and Australia shut down GSM networks, Nokia is supposed to turn down on a world standard? It doesn't mean that GSM is no longer a world standard as a cellular phone Network just because it is not available in Singapore.
The contrary, in some parts of this planet it still is available and sometimes it is the only available network providing important basic services like telephony and text messaging. Yes, also basic data services like GPRS and even EDGE are provided which allow you to check emails and even send WhatsApp message via GSM.
Telephony is one of the crucial services of a cellular phone network, you know, that is when you are in distress and urgently need help, you make a phone call rather than sending a WhatsApp voice message or using Viber or whatever. And GSM Networks, which are luckily still widely available in many countries, exactly can do that.
So, thank you Nokia for still supporting a world standard :-)
Well, it's both and... Unfortunately, SIM 2 (the nano SIM slot) is only active in the 2G (GSM) bands, i.e. 850 / 900 / 1800 / 1900. Data also is only possible with 4G via SIM 1 (the micro SIM slot). Only one SIM can be attached at once, either SIM 1 or SIM 2. During phone calls, one SIM is not reachable, either 1 or 2. Both SIMs can be paged for incoming phone calls.
Did I forget something?
Wow, that's interesting! And thank you, you did a lot of research.
You know, I didn't check all this for two reasons, while the first one is no really a reason:
1) When I go on data settings for mobile networks and try to set SIM 2 to 4G/3G/2G, the UI says that SIM 2 can only support 2G (and I believed that).
2) For me, personally, it's enough when one slot can support LTE. In that constellation I use one card as the data card for data transfers and as an emergency SIM in case the SIM in slot 2 has no network coverage, and I use the SIM in slot 2 mainly for phone calls and SMS.
So, my guess was that you can run everything from 2G through 4G data with slot 1 (depending on your choice under "data & network settings" with the phone trying to get the highest data rate possible, e.g. if 4G is available in a reasonable quality, it is preferred over 3G and 2G and so on) while slot 2 gives you 2G (GPRS and EDGE) plus voice calls and text messages...
Wow, thank you so much for that valuable piece of information! I will try this right away! You are right, concerning the specs of the X5 modem, but I wasn't too sure if HMD is going to offer it all via the UI or maybe block some features. Well, obviously, they didn't :-)
