Hello,
I am looking for a phone that supports dual WCDMA. Currently my "HTC Desire 600 dual sim" provides WCDMA only on SIM1.
The SIM2 is simply GSM.
I wish a phone where also the SIM2 offers WCDMA.
Background:
due to frequent traveling in 2 countries I am using SIM1 or SIM2 respectively.
On Country1 I have Internet using SIM1, but when residing in Country2 I need to turn ON Data-roaming (of SIM1) , or interchange SIM2 into SIM1's port (WCDMA) so that SIM2 will have Access to Internet.
This is really annoying.
Any Ideas?
Thx
PS: Sorry for duplicates, I opened this thread allthough I searched and found another similar question in this Forum, dated from last year.
That question was however not answered.

i don´t no if are any phone with 2 WCDMA
lg phones have the option for wcdma on both sim settings.. you can select any one sim as 3g but other sim has to be on 2g (without removing sims out of slots).. i have used e445/e715.. do check on specific model but most probably lg must be having that on all models..

That's a good hint with LG. Manually switching forth and back to WCDMA, but without need to interchange the sims, is something I can live with.

Hello,
I recently bought a Goophone X1 from Android-Sale.
I've got a problem with 3G connection. According to specifications, it should be compatible with WCDMA frequencies.
But when I put my sim card to slot 1, I can only choose TD-SCDMA mode. When putting it to slot 2, I can choose WCDMA but there's still no 3G (I think slot 2 is only 2G).
When going to engineer menu, I see that WCDMA frequencies are checked for SIM1 when 3G is enabled on SIM2, which is really useless. When 3G is enabled on SIM1, it changes to TD-SCDMA.
I don't know how to enable 3G on this phone. It seems to be a limitation of the ROM (or baseband ?).
Have you got any idea ?
Thank you.
I want to know too
I picked up a GooPhone X1 too, but it doesn't even recognize either SIM card slot. Email support claimed that their phones are incompatible with T-Mobile SIM cards, but I think what he meant was that only pentaband phones can access the 1700 MHz frequency that T-Mobile uses to transmit 3G and 4G data. Otherwise you are limited to 2G data.
And unfortunately, it looks like my phone is just broken.

same here.
Very odd , isnt it!
Its a new phone and I suspect we will be waiting a while until a rom with the proper activation of non chinese radio bands appears.
The hardware is obviously capable.
If someone has a stand alone MTK 6589 radio for another similar phone, it might be worth trying to flash the radio alone

You can try engineering mode either via mobile uncle mtk tool from google play store
or you can access it by dialing *#*#3646633#*#*
There are a lot of options to thinker with the GSM modem .
I have a x1.. I cant remember my password so cant acess anything!! Please help.. its ok if hard reset but I want the phone working!!! It refuses to go into cwm if I press the vol+ & power button! Please post adb drivers to use fladhtool

Hi all, did anyone successfully enable (switch) the WCDMA frequency on a TD-SCDMA phone through hahomir4ev's method???
Any suggestion would be helpful!!!
Is the second SIM WCDMA 3G voice capable or is it only GSM as most dual-sim phones out there?
I can't seem to find any information on it, and this is an important piece of data for people living in countries with no 2G GSM network.
The second sim is GSM.

In other words, useless for Japan (where all voice calls go over WCDMA and there is no GSM network).

You are right in that it is useless in Japan. However, just to clarify the issue: Both SIM slots are 3g capable, but the phone forces the SIM card that is not used for data to 2g mode. Only one of the SIMs can be used for data at a time, just as you can only send texts or make voice calls through one at a time so it makes sense in any other country...
What is not clear is whether this is a Motorola decision to save battery or imposed by the chip set used or an Android OS issue. Covia Fleaphone has same issue, and provides a shortcut to switch the active SIM (active=3g enabled SIM), so it seems to be not just a Motorola decision...

I believe it has only one 3g radio in it and used by whatever Sim is being used for data So its a hardware issue

Sounds about right... It is a real pity how bad the documentation/specifications info is on dual sim phones. Make it very difficult to pick the right one, several people now claim that the Xperia M2 works with 3g on both SIMs simultaneously, but can't verify this...
At the same time I guess Japan (where I use it) is an unusual case, most places still have 2g, and Japan only recently started selling separate SIMs...

Hey guys,
So I have the Z3 Dual, but where I live, we only get 3G network and no GSM, which brings me to my question:
Is anyone working towards a hack to allow my device to run BOTH my Telstra SIM cards in LTE mode without one reverting to GSM?
Thanks in advance,
Phil
Really? No gsm signal or 2g. I think 2g structures are the most basic one that every carrier Has. BecAuse if 3g becomes congested, the subscriber can fall back to 2g. Anyway i guess no hack is on going because of the rooting issues with this plus i think it's a hardware limitation. 2 simcards cannot use 1 modem (the 3g/4g) because that would tax a lot of battery power

There are 2 radios in the phone I'm suspecting, since both SIM's run different IMEI numbers (1 per radio) if you check in About Phone/Status and check the 2 SIMs.
So I can't see why this is a limitation.... renders the phone worthless for what I wanted it for (Work sim and Personal sim),
And yes, where I live, there has never been GSM, it was CDMA before the towers were upgraded to 3G (Central Wheatbelt is Western Australia).

When you use the first SIM with LTE the second has no signal?
I can't understand if the second sim limit is only for connection or also for 3G bands.
I mean: you can still use the second line on a 3G network only for calls and SMS without using data connection or not? The second line is limited on 2G bands?
thanks for answers I ordered a Z3 Dual 2 days ago

Correct, because the second sim drops down to GSM, which we don't have in rural Western Australia. And vice versa, set the second SIM to LTE/WCDMA and the first SIM drops down to GSM. Meaning, you cannot run 2 SIM's side-by-side unless you live in an area that has GSM/2G still.

So, you choose either SIM as your data sim. Whichever you choose, that sim runs in LTE mode and the other SIM is used for calls/sms only.
SMS and phone apps both have 2 send buttons labelled 1 and 2, so you can send messages or make calls from either SIM at the press of a button. But only 1 SIM has data active, that is the SIM running in LTE mode.
I have messaged Sony Mobile Developers regarding this, the reply was:

Thanks for infos!
That's weird! If I live in a place with only 2G or only 3G network I cannot use 2 sim cards!
But I remember reading on online user manual that the 2 sims network settings are separated, right? If you force both on the right frequency?
In a few days I'll receive the phone and I'll help you with some tests

Correct, both sims wont run on 3G at the same time..
Both sims WILL run on 2G at the same time though (GSM).
I have a question about dual sim model. Do both sim card can work simultaneously eg. 3G like eg Xiaomi 5?
Most of dual models work with mode (2,3,4)G/2G or 2G/(2,3,4)G only.
Regards
One SIM must be in 2G. The other can be 2G/3G/4G.

Is that 2g , so no data phone only or just gprs?
I meant 2G as in phone or SMS only.

Any idea why is this limitation? I was trying to see it to LTE mainly to put that in VoLTE for calls and then realised either of the SIM only can be set to LTE.
On the XZ, I have sim1 on 4g and sim2 on 3g.

I've asked the same question to a Xperia rep. when I've purchased XZ dual in Hong Kong.
Both slots are 4G speeds, but if both slots are in use; highest speed of one slot is 4G and other limited to 3G max
They don't have 4G/4G support yet...
Hope this helps.
Well I was going to start a new thread, but this seems like the correct place to ask:
So if I have one sim dedicated to calls/text and a second sim just for data, the phone should operate the same as if I had only one sim which can do both phone and data?
Also if both sims are capable of handling calls, can i deactivate the phone of one sim card but keep the data active?
Hello. I am an owner of Huawei P7-L00 (dual sim). I have a problem with sim slot 1 with many signal disconnections. My phone is also for FDD-LTE & TDD-LTE band. I had a contact with my provider and told me that the possible reason is that sometimes my phone tries to find the default 4G band (TDD) that is not supported in Greece. Othertimes succeed to make a search to find the optional band (FDD) that is supported in Greece and is supported by phone too and other times doesn't succeed to make a search and I lose my signal. Could you inform me how can I change the default band to (FDD) or how can I delete the app or the process which making this searching? Any other opinion of the problem, please?
Thanks in advance!
