3G - General Topics

Is my XDA IIs 3G?

no
it's
not

So if i put a 3G o2 sim card that i have in it what will happen?

You phone will work, that SIM card just enables you to use a 3G phone as well as other non 3G frequencies.

but some operators like the company 3 seem to block their sims from working in non 3g phones

[Q] hardware differences between US verizon 3g and UK 3g

Hello all
i have a verizon 3g xoom. it's not upgraded yet. i live outside us
about the UK 3g xoom, can it operate 2g sim card? for sms, gprs or ...
how about normal 3g sim cards?
is there any hardware difference between mine and uk one?
may i operate my 2g sim card on my xoom? how about 3g?
when i put sim card nothing happen. i just tried 2g sim card
our 3g operator is not started selling sim cards ... but we have 4g operator.
if i install uk xoom's rom on my own, can i use sim card?
is there any mini pci-e card that i can use my sim card with it? (self upgrade xoom with custom mini-pci-e)
please help me. i need some information. i'm confused.

how about this thread? i've done that but dont work for me. there is no signal, i think it didnt recognized my sim card.
if i install the mini-pci-e card that motorola installs on xoom during upgrade, can i use sim card for 2g/3g ? (sms or internet)
i have found this : "If you bought your Xoom from Verizon, it will have no SIM card slot. Verizon's CDMA network doesn't use SIM cards. Also, if you bought the Verizom model, it will only work on Verizon, and not another carrier. There is also a WiFi-Only Xoom, and it does not have a SIM slot."
here : "http://www.ifixit.com/Answers/View/53440/Why+I+can%27t+find+3G+SIM+Slot+in+my+Motorola+Xoom"
but mine have sim slot with a plastic sim on it.
The Verizon 3G Xoom does have a sim card slot but no hardware inside to read the sim card. That is what the 4G upgrade was for, to install the hardware necessary to utilize the sim card for the Verizon 4G LTE network.
I don't know if anyone has gotten a Verizon Xoom working on any other carriers network.
Theres pix of the inside of my Uk3g Zoom somewhere...

[Q] Sprint LTE SIM in 3G phone

Is it possible to get only 3g on a 3g phone by switching it with a LTE sim card from sprint, and NOT activating it with them (not telling them the switch)?

[Q] Dual sim, 3G on both sims smultaneously - does such rarity exist?

Hello, for the last couple of days I've been on the hunt for a dualsim smartphone that can receive 3G signal on both of its sims, simultaneously.
At the moment I own a device that can do 3G/2G for sim1, only 2G for sim 2 and I have to use 2x3G sim cards(the provider emits exclusively 3G signal for mobile communications); in this scenario, one sim card is unusable.
Now my question emerges: is there such thing that can certainly(I can't afford to just buy devices that could possibly do this based on ambiguous internet discussions and test them out) keep 2 sims, both 3G, operational simnultaneously(not with the tricky switch, I will be needing to get calls on one of the sims, even if the other goes to standby)?
Thanks!

Simple sim data switch

Hello fellow members, I have a bit of a more complicated problem.
I have a dual sim Moto G2 capable of handling one sim in 3g network and the other in 2g network. In SIM slot 1 I have a Digi.Mobil sim card with unlimited data. In SIM slot 2 I have an Orange sim card with few GB of data.
The Digi.Mobil sim card gives me no signal when I am at my office so I need to use the Orange sim card to be reachable. To use the Orange sim card I have to go to settings and manually select it as the data sim. This makes the Orange sim as the 3g sim and the Digi sim as 2g sim.
When I leave work I could leave the Orange sim as the data sim with 3g and Digi sim as 2g. The problem is that the Digi network does not accept 2g. Only 3g or 4g. This means that for the Digi sim to work I have to switch it back as 3g and use the Orange as 2g and use data from the Digi sim.
Is there like a super simple widget or way to just say: OK now i want to have net from Digi and automatically set it as 3g, and now I want to have net from Orange and set that one as 3g? Or is there a way to have 3g as preffered network for Digi while using data from Orange as 2g?
I know the problem is a bit complicated but I really appreciate any help on this.

Dual SIM 4G+3G or only 4G+2G ?

I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...
If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.

3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.
4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.
