[Q] Dual mode standby? - Droid 2 Global General

I intend to buy a Droid 2 Global and re-programme it for my network in Nigeria (Visafone). I've done this successfully for a couple of CDMA phones; I know what I am doing on that one, but I have a question. I see that the Droid 2 Global is a dual mode phone GSM/CDMA. Is this like the BB Storm 2 or is it dual standby, like both networks work at the same time just like the Motorola XT800? I've been searching for a dual mode, dual standby Android phone and I figured I would go with the Droid 2 Global, if it is really dual standby. Please can anyone help me clear this up so I can make a decision about buying the phone on ebay.
Thanks everyone.

The A956 (D2G) only has one transceiver that can work in either GSM or CDMA mode. In Global mode, CDMA is preferred (if there's CDMA reception, the phone will use CDMA).

[Q] Droid 2 Global unlocked, but how to unlock Droid 3 ?

Hello,
I am lucky user of full unlocked D2G... it was activated for global using by verizon and then fully unlocked by NCK code for all GSM networks.
But now is Droid 3 out on sale and i need it
My question is :
Is possible unlock it with the same procedure or not ?
Thank you for all replies
I haven't yet heard of any unlock code databases for D3 leaking.
D3 (seems to) is not a global phone, so it doesn't have a SIM slot.
It's not possible to unlock.
Wait for Droid 3 global maybe....

Droid 3 is a GSM/CDMA phone and has a SIM slot.
Please at least read the technical specifications first.

...yes
droid 3 is GLOBAL phone with this specs.:
2G Network GSM 850 / 900 / 1800 / 1900
CDMA 800 / 1900
3G Network HSDPA 850 / 1900 / 2100
CDMA2000 1xEV-DO
I am on GSM 900/1800 in europe
like this:
Code sites cannot supply unlock codes yet. Give it a week or two, things might change.
@wondereye - Droid 3 is a global phone. It uses the same chipset as Droid 2 Global (QUALCOMM MSM6600 if I am not mistaken).
This only horrifies me since we all know how BAD Droid 2 Global is with (most) UTMS networks. Based on the first responses over @Droidforums D3 seems to show dangerously similar signs of unstable baseband just as D2G has.
Personally I am thinking I will hold my breath for a pure native GSM/UTMS only Milestone 3 or XT860 or whatever it is called this time.
I have no problems with using my D2G on 2G/3G network in my country.
It is true that when i have switched to GSM/UMTS mode for 3G internet, then is signal strength bar low.
...but the signal bar is laiyng. In service menu is signal good and approx same as on another android phone.

HTC Thunderbolt Unlock to work with GSM?

I have an HTC Thunderbolt from Verizon. I reckon somehow it is compatible to work on GSM networks, I have done a search on this but I kind of got lost, please read the following and tell me your opinion and if you think HTC Thunderbolt is capable of working on GSM. By the way i am no expert just the contrary I have very limited knowledge with these stuff...
First of all before everybody jumps into a conclusion; I know Thunderbolt is listed as a CDMA/LTE phone thus, it will not work on GSM networks. According to my understanding, what makes a phone compatible to work on CDMA, GSM etc is;
1. The Hardware: ie Chipset, GSM Antenna etc
2. The Software: The version of the software, Android™ 2.2 etc.
Here is the deal, HTC Thunderbolt has "Qualcomm® MSM8655, 1GHz, Qualcomm MDM9600" chipset, MSM8655 is basically for voice and MDM9600 is for LTE which is data. According to Qualcomm; msm 8655 chipset is GSM capable. Also according to Verizon; Droid 2 by HTC is also global ready meaning it is GSM and CDMA capable. Now here is the trick; BOTH HTC THUNDERBOLT and DROID 2 by HTC have same chipsets yes "Qualcomm msm 8655". So I would say on paper, Thunderbolts chipset is GSM capable. But what about the GSM antenna, I think Thunderbolt also has a GSM antenna; thus when I enter *#*#4636#*#* and go into testing and phone information. You see GSM service: Emergency call only not to mention there is an option in the setting where you can turn on and off the GSM radio. When GSM radio turned off you see GSM service: Radio off. I have also figured when you insert a GSM sim card into the Thunderbolts sim slot, you can update SMSC numbers from the GSM sim card; you can also import contacts you have in the sim card. SO Thunderbolt definitely reads the GSM sim card and has GSM radio integrated.
So overall Thunderbolt hardware wise has everything needed to operate on GSM networks. Let’s see the software. According to HTC; Thunderbolt has Android™ 2.2 + HTC Sense™
Current software number: 2.11.605.5. and Global Ready HTC Droid 2 by HTC has Android™ 2.3.4 (Gingerbread) with HTC Sense™ Current software number: 4.08.605.3. So 2 different software.
Let’s go into more tech android stuff, according to some forums, if you add a new radio and rom that enables GSM option, some cdma phones actually will work as gsm phone. One sample is Miui rom...
I will go ahead and try this Miui thing, Please give me your thoughts....
this thread hould listed on htc thunderbolt section.
however i think GSM still need hardware support..not only using software...but who knows..i'm just ordinary people too..not an technician hehe
HTC Thunderbolt (ADR6400L) is GSM or not?
Does anyone know about this?
I want to know if this phone could work on GSM networks, I have entered the service info *#*#4636#*#* and I found GSM service and GPRS Service which are from GSM. but in set preferred network type GSM in not listed.
any light on this?
From what I understand, the radio chipset may indeed support GSM, but not in the way that you think. LTE is a GSM-type network (it is based on GSM, hence the LTE SIM cards), however, until we have VOLTE (Voice Over LTE) sometime late this year or next, it won't work. Perhaps there is a radio software that could theoretically talk on GSM, but I don't think this particular chipset supports it, as it talks on a different frequency. I may be proven wrong, but I think that's how it goes...
how did miui worked out for you???

Its possible
Hello everyone,
this is my very first post here, and I came across this thread as I'm looking for a similar but yet different solution
Just wanted to add in that I have a TB currently with voice, text and 3G data in Mexico with Iusacell...
Im not quite sure how it was done but I'll try to contact the person who pulled it off...
but just wanted to say it was possible to get the TB working on another CDMA company...

I use iusacell to but where i live, the cdma network doesn't have much coverage.
So i want to know if i can call over the gsm network and use the cdma to navigate on the internet.
P.S.
What do you mean by TB?

I think this is a Verizon only phone and would SPECIFICALLY, even with the chipset, WORK WITH ONLY VERIZON. So I don't think it matters with the hardware, Verizon probably somehow locked the chipset to Verizon even thought it's GSM-compatible. There are also no accounts of anyone who had unlocked the phone and get the phone working with GSM carriers. It's very unfortunate, as the phone looks awesome and performs solid.

Verizon DROID 2 to GSM 1900/900 Optus Network?

Hey Guys, I'm interested in getting one of those R2D2 DROID 2 phones and I wish to use it on the optus network in Australia.
I believe optus uses a dual band 900/1900mhz ?
Some questions I have are too people that have tried this already.
Will the 3G data work on this phone?
How difficult and what modding needs to be done on this phone to get it too work?
Thanks for the help peeps : )
Let me get this straight.
You're asking whether you can use DROID2 R2D2 (a CDMA-only device that supports CDMA2000 and 3G CDMA 1x EV-DO Rev.A) on Optus's GSM network operating on 900/1800MHz bands with 3G UMTS/HSPA?
So, you want to use a pure CDMA device with no GSM support whatsoever on a GSM network, right?
Hardware wise this is almost identical to the milestone 2 right? I've heard that in other countries with the Verizon phone roaming is enabled so it would work with other networks? Excuse the noob question. How is cdma different to GSM?
Sent from my U8160 using XDA
CDMA is one standard. GSM is another. There is almost nothing similar between these. Here's a question: how do you fit a GSM SIM card into a DROID2 R2D2? It has no SIM card slot.
Verizon CDMA devices can roam on CDMA networks.
Verizon Global phones can use GSM networks, because they have a GSM+CDMA transceiver in them.
The DROID2 (and the R2D2 variant) isn't a Global device.
The DROID2 GLOBAL is.
Please refer to http://en.wikipedia.org/wiki/CDMA2000 and http://en.wikipedia.org/wiki/GSM so that you can stop asking these… weird questions.
How is it a weird question?
Some have modded/flashed the DROID 4 which is CDMA phone to work on GSM.
I am merely asking if its possible or if anyone's tried it.
DROID4 is a Global device. It has a CDMA+GSM+LTE transceiver.
DROID2 doesn't.

Dual sim, one sim always 2G

Hello all,
I'm a dual sim user for some time now.
Currently I'm looking for a replacement for my Allview P5Quad (rebrand of Gionee gn708w, same as Xolo Q800), which slowly but steadily gets to the end of it's usable life.
I'm currently looking at another dual-sim, the Gionee Marathon M5 (rebranded as Allview P8 Energy in Romania).
BUT I see that after all this time the operating of dual-sim devices like these is still the same. One Sim set as available for 3g(or 4g if available) and the other one locked on 2g only.
This was not a big concern until now, but in my country 4g rollout is quite fast, 3g gets better AND due to this lately 2g is becoming more and more ****ty and unusable even for voice only, due to being discretely phased out.
Is there a dual sim phone that would support a combination of sims like 4g+3g or at least 3g+3g, or even better (dreaming) 4g+4g?
Is this limitation hw or sw?
Afaik it is a hw design limit in the chipset. If so, anybody has any idea on why do manufacturers stick to this way when 2g is going out and 3g and 4g are so present in our lives?
Thanks.
