    Dual sim phone, more complicated than I thought, anyone help?

    Dual sim phone, more complicated than I thought, anyone help? 19th Apr 17 at 7:48 PM
    Need someone who is a bit techy to help with this please.
    I have a personal phone contract with Tesco, had it for years, love it.
    I have a PAYG Sim from Three, which is used so that I can work from home/ have flexible office hours. It is a number which can be given to my company's customers, so they can call me. I don't use any data on it, and very rarely call/text out, as I have plenty of capacity to do that on my personal contract if necessary - or I call them when I am back in the office. I chose Three because any money we put on the sim doesn't expire after a month, AND because they have WiFi calling (Three in Touch), useful cos mobile reception in my house can be a bit dodgy.

    So for the last few months I've been carrying 2 phones about with me, a pain in the bum. I've treated myself to a shiny new Moto g5 which takes 2 sims. my intention was that my tesco sim would be my Primary sim - all outgoing calls/texts and data would use that sim, and the Three sim would be secondary, simply there to receive calls.

    BUT .... the Three sim won't work as the secondary sim. After a lot of faffing about and chats with three support over twitter, I find that this is because whichever sim is set as the secondary sim only uses 2g - and Three no longer uses 2g - so I can't make this work as I'd like to.

    So .. techy experts out there - do you know if any of the networks still support 2g, and have wifi calling (is that even technically possible)? If they also have PAYG which doesn't expire that would be icing on the cake - but I think I'm pushing the boundaries too far with that .

    I feel like a right chump at the moment, cos the dual sim phone was a right waste of money
    I try not to get too stressed out on the forum. I won't argue, i'll just leave a thread if you don't like what I say.

    However, not all providers support WiFi calling, do they?

    Unless they have changed something with the G5 then Three are lying

    I have a G4 and with a three PAYG as second sim I can make and receive calls and texts using it

    Most dual sim phones used to only support 3G/4G on one sim, and 2G on the other. The three sim won't work on 2G.

    Moto G4 was the first I found that could support 3G on both sims at same time.

    Perhaps Moto G5 has reverted to cheaper hardware which doesn't support dual 3g.

    According to the specs at http://gadgets.ndtv.com/lg-g5-3308 it is the same as the G4 as far as sim 1/2 capability is concerned

    On a dual SIM phone, you can pick which SIM/slot to use when making an outgoing call. A temporary SIM swap would soon determine if the Three SIM was OK in that particular phone, although I appreciate you might want to use the other SIM for data.

    A friend has a Samsung dual SIM phone, but only uses WiFi data, and doesn't use a Three SIM. On that phone, I think the slots can be renamed from the default of "1" and "2".

    To be fair to Three and needing a 3G or 4G phone, 2G is so last century. I read somewhere that the other networks would soon be turning off their 2G, although when/if is another matter. See:

    Can you designate either SIM to be the one that pulls in the internet when not on wi-fi?

    Unlikely, if it works in a similar manner to my friends Samsung, one slot is 2G only, so the other one is the data/internet one.

    On a G4 you can select which SIM for data, both slots do 4G.
    For calls and text you can have it sim1,sim2 or choose on a per call/text basis. Each can be set independently.

    If you want you can have something like sim1 for calls, choose for text and sim2 for data

    Most dual SIM handsets are 'dual standby', where calls and texts can be received on either SIM regardless of which one is selected for data.

    However the SIM which is not being used for data connection will operate only on 2G - The only exception (reportedly) being the Moto G4, which somehow gives 3G/4G connectivity for both SIMs at the same time.

    The OP's problem with using a Three SIM as the non-data SIM in a dual SIM Moto G5 indicates that the unique characteristic of the G4 has not been carried over to the G5, which is a pity.

    In Singapore all 2G networks have already been discontinued since February, which means that a dual SIM phone can now only operate on one SIM at a time. However, I read somewhere that in UK the 3G networks are due to be switched off before 2G.

    Convenience for travelers and other dual SIM users will be lost if countries phase out their 2G networks, and handsets with the Moto G4's particular dual SIM capability are no longer available.

    The Moto G5 user guide can be downloaded here:
    http://www.gsmarc.com/motorola/moto-g5/manual/

    It mentions dual SIM, or rather how to insert 2 SIMs, but no info on their use... unless I missed something.

    I don't know the G4/G5, but I do have a dual sim Samsung Galaxy S7.


    It's a singapore model (dual sim not available in UK), that I "flashed UK rom" onto (for those who understand what I mean - this doesn't 'Trip Knox').


    With this setup, I could choose (and change at will), the primary outgoing phone, outgoing text, and outgoing data. Sim 1 can handle 2G/3G/4G, and Sim2 can handle 2G/3G. I had my company sim (vodafone) in Sim 1, and my private (O2) in Sim 2. Only issue I encountered was that switching the data between them upset my companies' BYOD software (Mobile iron) policies which meant it'd block my phone from receiving company email until they reset something on the server.

    Thanks for all your interesting comments.
    Can anyone actually answer the question I posed ?

    do you know if any of the networks still support 2g, and have wifi calling (is that even technically possible)? If they also have PAYG which doesn't expire that would be icing on the cake

    Your first reply answered the first part. All main networks and MVNOs work on 2G, except Three (and presumably any MVNO that uses Three). As for WiFi calling I'm not sure, but all main networks probably provide it in some form. All provide PAYG.

    You may find a network that works ok in your house, by ordering free PAYG SIMs from each one and trying them in your phone for 2G reception.

    Most of them require you to top up a minimum amount every 6 months to keep number live

    Your supposition is right, the G5 has had cost cutting and uses older dual sim hardware that only allows 2G on sim2.
