    Dual SIM phone limitations

    Dual SIM phone limitations 11th Oct 17 at 2:24 PM
    I've been looking at buying a dual-SIM phone for one specific reason: getting the best possible data coverage in remote parts of the UK.

    Until a short while ago I was planning to buy a Motorola G5 dual-SIM, but the feedback about the limitations in how this works makes me worry that it won't work as I want it to.

    I want to be able to use a Three 123 PAYG SIM in the first SIM slot (for phone calls and as a backup for data, tethered to a laptop) and the second SIM slot for an EE PAYG data SIM (tethered to a laptop).

    Will this work, or will the EE SIM only work at 2G speeds?

    I should add that I've already considered a Dual-SIM Moto G4 - given that it seems to be one of the few budget smartphones that supports 3G/4G properly on both SIM slots - but I don't want a phone any bigger than 5" (or 5.2" at most)!

    There's nothing to stop you setting the phone as a hotspot, indeed there's nothing Three or any provider can do about that as its a feature baked into Android and I dare say iOS and Windows Phone too.

    My traffic is only light website use and email, so perhaps I'm not generating enough to trigger the limit. Thanks - worth knowing though, as I now know to keep usage low when I can't get coverage on the MiFi limpet.

    I'm dithering now. I almost went for a Moto G4 dual-SIM but it's a little bigger than I want, and it doesn't get good reviews for reliability either - rather like the G5.

    I've got a Lenovo P2 and I'm really happy with it. Dual SIM (Gifgaff and Three) and I get great speeds from either as far as I'm concerned. Also the battery life is fantastic, I easily get 2 days with moderate use and it's even got a Power Save feature which quickly turns it into a dumb phone which can be useful when the power is really low.

    Also I was reading the the new Pixel phone will be dual SIM, one is a virtual (eSim) and then a physical one.

    Hmm, I'm sure that it does. Do you mean if I move from Giffgaff to Three via the Settings > Sim Management > Mobile Data? If so, then I've definitely had 3G on the Three SIM which is my backup one and I get 4G from the Giffgaff. Or have I misunderstood the issue?

    No, do you get 3 or 4G on both SIMs at the same time. On my G5 I get a HSDPA or 4G symbol by one of the signal bar graph say for 3 and no symbol by the other signal bar graph say for O2 i.e. 2G.

    I see the updated image but what about on the screen itself on the status bar?

    Sadly the time has passed to get a Lenovo P2 at a sensible price, and the new Pixel won't be in my budget either.

    I almost went for a Wileyfox Swift 2 Plus earlier this eve. I could find no statement either way whether it supports 2 SIMs properly, but... the battery life is something I could not live with.

    Probably back to the Moto G4 but I really don't want a big white phone (possibly due to the 70s euphemism "talking into the big white telephone")! More prevarication...

    To me, your problem seems to have been caused by your insistence on using your SIMs the wrong way round! The EE should be the back-up because 3 do 1 month rolling contracts for calls + data which allow tethering, if you don't want to commit. If you do, there are some excellent 12 month deals with unlimited mins and 4GB data for £9 pm or 12GB for £12pm. If you can get the £60 Topcashback for the latter, then that works out at £7pm, and you can tether the lot. For the former, it's £5.67. Even for the much smaller amounts of data you may actually need, I expect you are paying through the nose with EE PAYG.

    Thanks - but I don't think in my case it makes a huge amount of difference either way!

    My spend on Three for voice/text use is probably £2/month on their PAYG 123 tariff. I use a fixed cost PAYG data SIM for the times I'm away from home for 3-4 weeks at a time, when a 2GB 30day SIM is about as cheap as it gets. Whichever way I do it, my yearly spend is going to be around £20, which is Ok by me, but I bet no mobile operator actually wants my business very badly!

    Anyway, I've just bought a Moto G4 Dual-SIM (£149 from John Lewis with 2 year warranty), plus a replacement back case in black as I don't want a white phone. I may live to regret it in terms of reliability, but I can live without a phone for a few days at a time and it won't kill me!

    I've never heard that 1970s euphemism and I thought that you maybe got confused with 'white van man'
    A bit of digging reveals that this image is one you might have wanted to avoid....

    The phone you bought is available in black or white, so maybe people might wonder why you chose the white one!
    Reviewer Nick from Staffs explains...
    Note This white version of this phone is correctly described in the product description as dual Sim. If dual Sim is important to you do not be tempted, as I was, to buy the black version after assurances from JL's online customer adviser that the only difference in the two is the colour. The black version of this phone is NOT dual Sim, or at least the one I bought wasn't, despite some reviews for the black version saying they are. In fairness to John Lewis the product description for the black one makes no mention of dual Sim.

    There are some Chinese phones which apparently will support two 3/4G SIMs for both voice and data at the same time, but I am wary of purchasing them due to warranty issues.

    And yes - I went for white for that very reason! I think it's going to look a bit odd with a white front, a silver bezel and a black back, but I'll live with it, as long as it works as advertised...

    My interest in this thread is that I have a similar problem in that I want to use a 3 SIM for data (and cross network calls out) with my o2 PayUpfrontForLife SIM (for receiving calls, mainly). I have just come across a device which I didn't know existed, namely https://www.tesco.com/direct/dual-sim-bluetooth-adapter-credit-card-size-works-with-android-ios/790-0377.prd?skuId=790-0377
    Although this is too late for the OP, he did say -
    The aim was to get a single device to do everything so I don't have two devices to keep charged.
    But as I said earlier, if there is not simple single-device solution I may just as well stick with what I have.

    However, although one has to keep this second gadget charged, it is thin enough to slip into a wallet meaning it's not really an extra item to carry. This gives a measure of security if either is stolen, as an alarm is sounded when the bluetooth connection is broken (presumably a maximum of 10 metres). This would enable a thief to be pursued, as he would be carrying an alarmed wallet (although in a crowded area, I'm presuming the alarm would switch off as you got closer than 10 metres leaving several people as the possible culprit ). If it's the phone that's stolen, then you'd have little chance in a crowd as you'd be carrying the alarm.

    Introducing PIECE, a credit card-sized device that basically lets you add an extra number to your existing Smartphone. Its ideal for those who own two phones, one for work and one for your personal life, or people who like to travel a lot and want to avoid costly roaming charges. Simply insert your extra sim card into PIECE, connect via your smart device and control your new sim card with the dedicated PIECE app. PIECE is designed to work with any Bluetooth-enabled Android or iOS device including tablets.
    CONTROL VIA USING THE APP
    Once youve inserted a SIM card into PIECE, you can then pair it with your existing Smarphone using the dedicated PIECE app, where youll be able to add all your contacts and make calls and SMS messages. Plus, the app lets you know the status and remaining power of your battery in real time.
    SMALL YET MIGHTY
    PIECE has been designed to be as thin as possible so that it fits seamlessly in your pocket or wallet. Despite its compact size, PIECE features a rechargeable 550mAh lithium ion battery that boasts up to 150 hours on standby.
    FIND YOU PHONE OR WALLET
    Use PIECE to locate your smartphone or vice-versa. This handy device features a distance triggered alarm system that sounds if your Smartphone and PIECE are ever more than 10m apart. Perfect for those who are prone to losing their phones or wallets.
    - Add an extra number to your existing Smartphone
    - Compatible with any Bluetooth-enabled Android or iOS device including tablets
    - Small enough to fit into your wallet or pocket
    - Bluetooth 4.0 connectivity
    - Impressive battery - Up to 150 hours standby
    - Sounds an alarm when smartphone over 10m apart

    Interesting - though obviously too late for me. But I can't quite figure out how it works. I suspect it has no modem of its own - it simply passes the SIM identity info via Bluetooth to the "host" phone? But it's not too clear from the description. If so, it would not appear to allow two SIMs to be active at the same time...

    As the O2 contract doesn't include data, you wouldn't have quite the same dilemma when using a dual SIM phone, as you could have the O2 one on 2g all the time.

    Or if you don't have a dual SIM phone yet, just carry an old Nokia (which you might be doing already).

    But another option which you possibly don't know about yet is O2's TU Go, which you install as an app on Android or iPhone, or it even works via some web browsers, and it can then handle all your O2 calls and text messages, via a data connection. So you don't need the O2 SIM with you, though if it is still in another phone, they can both ring.

    Try it for a while. £40 cheaper than that gizmo.

    £40 is more than the cheapest unlocked smartphone so I bloomin' well expect it to have its own modem! If it didn't, how would an O2 signal reach it when there's a 3 SIM installed in the smartphone's only slot?

    In case you're not aware, your existing phone's modem can receive a signal from all of the operators, all of the time. The SIM just tells the phone which of those channels it's "allowed" to use (because the SIM proves that you have a contract with that operator) and which you're not. That's why you can make 999 calls with any SIM on any operator's network, even when you are out of range of a transmitter owned by the network that your SIM shows you subscribe to.

    Hence my contention that the device ~might~ work by just allowing your phone's modem to use the identity data in the "remote" device's SIM (rather than having a modem of its own).
