Dual sim working on desire

Bought a dual sim adaptor from ebay for 6 quid.20th edition magic sim where you don't cut the sim.working fine...able to access stk menu, but only works if you change network settings to gsm only.will not work on edge or other speeds.but at least it works! Only thing that's a pain is every time I switch sims I have tof keep putting password in for google mail.if you download the app multi sim from market you can set up a little icon for each specific sim number so you know whatnumber is being used.
Might see if I can find adaptor that uses other speeds but not paying silly money.

Hello,
I am very interested in a dual sim adaptor. Can you please post a link to the vendor
P.S Has anybody tried this :
Dual sim card 26th-B 3G dual sim, they claim that it works with 3G also

Great stuff keep us informed, so you don't have to reboot the phone to switch and it fits under the battery?

it is working great with umts. no rebooting. perfect stuff

I really don't know if i feel like cutting!!!! my sim card to pieces
Besides - how will wavesecure act to this changing sim all the time ?
Smirge

Wave secure works fine.you need to add the 2nd number to your safe numbers.I have it installed on my phone.you don't need to reset phone to switch numbers.just click on the sim number you want to be live.
As I stated g works at moment.need to find one that works with hpsda etc.will post link later to one I purchased.
Its the one where you don't need to cut sim so all good.

and it rewuires you to cut the sims, very easy as you get a template.
It works- both sims work with Hpsda,3g etc- full internet and the usual fast speeds -unlike the previous adaptor i tried which would ionly allow gprs.
You can switch via the sim tool -which doesnt restart the phone-takes about 12 seconds to switch numbers- works great with wave-secure

Can anyone who has a dual sim working with 3G please confirm, and link to a source. I've tried these before and never had a satisfactory experience. I'd try them again, but want to be sure that they are fully working (for phone and data) before spending even more money on an imperfect solution.
I don't mind cutting SIM's as I have a press tool that does it cleanly - as long as that wont damage current sims. Will my old tool work with current sims? I'm assuming that the footprint and location of the chip hasn't changed in current generation sims?
Also, is it possible to log into one gmail account with one sim, and another with the other sim?

i have just confirmed -see above!
with link also...as advised earlier hpsda works,3g works, everything full internet works.
You have to enter password again for Google market- when you switch. but no other problems.
using both vodafone monthly contracts in the uk.
Also works on my n900 also bonus

-deleted- (didn't see the new page)

I'm certain the answer is no, but I take it this doesn't allow you to recieve calls on both numbers at all times? In other words, the only thing this avoids is having to turn off the phone to swap sims - there are no other advantages?
A long shot really - I get sick of carrying around two phones (One is corporate, the other personal)

yep one phone number at a time..still better than carrying 2 phones though.
No problem with messages either- it seems to save messages from both sims.
not happy about the £36 for unit ,but glad it works

Any one get a dual sim working for desire on 3uk hsdpa speed

i was going to get new mifi unit so i could use my 3uk 5gb monthly mobile broadband allowance
but if my main mobile 3uk sim (500mb internet)and 3uk mobile broadband sim (5gb)works with a dual sim, then obviously save me a few bucks
can somebody verify duals sims with 3uk

First of all thank you for sharing with us your findings.
Now here is the scenario: I have a voice only (as in no data plan) SIM and a data only SIM (from a USB stick). I have tested the data SIM, it works just fine in my Desire with the correct APN settings, of course I can't make any calls with it.
Question: would it be possible to use a Dual-SIM adapter so that calls are made from one card and data (APN settings) are from the other SIM? I mean use them SIMULTANEOUSLY without switching from one SIM to the other.
P.S. It's more of an "academic" interest for me as I do have a data plan but since data only SIMs are now free on some networks (RDS in Romania) it would be a nice alternative.

nope it would still need to be switched in order to use other sim data. you can only use 1 sim at a time

[Q] Not your everyday "Your SIM card does not allow..." problem

Hey guys!
So, I can clearly see this "Your SIM card does not allow a connection to this network" problem is quite common around here, so here we go.
After one year of normal use, I got my problem one day ago, no connection whatsoever since then.
Tried shutting it down, removing the battery and switching back on after 20 minutes.
Tried my sim card in another phone - Works fine.
Tried another sim card, from the same operator, in my phone - Works fine (WTF)
I then called my operator (it's a Brazilian operator so no matter mentioning it now) and of course, no solution. Payment is fine, everything normal.
So I wen't to my operator store and replaced the sim and... Still doesn't work!
I then borrowed a sim from another operator and... Nothing! No signal!
And just now, I realized that, when I change to "GSM Only" it works! The thing is I have an unlimited 3G plan, and use it a lot, this is not a solution for me.
I've always used my phone on "WCDMA Only" or "WCDMA Preffered", but when I switch to those, or to anything other than "GSM Only", it dies, no signal, even with GSM Auto...
I tried hard resetting, nothing helps here... I have no idea what to do next.
When on WCDMA Only:
Signal Strength: -71 dBm 21 asu
GSM Service: Emergency calls only
GPRS Service: Disconnected
Network Type : unknown
I bought the Phone brand new on eBay (or rather a brazilian version called Mercado Livre) and it's clearly from the UK (i can see from its plugs) but it's unbranded and unrooted, but unlocked.
Also. I heard this may happen with stolen phones, blacklisted IMEI's... How can I figure this out? And how does that explain the fact it works under GSM only?

Just searched my IMEI on different databases, doesn't seem to be stolen.

This is swelling my brain to the point I think it's gonna blow.
My Phone Sim Card (TIM Network) - Works on any phone, and works in my tablet, but not on my DHD.
My Tablet Sim Card (VIVO Network) - Works on my phone, and work on my tablet.
My friend's Sim Card (TIM Network) - Works on his and my phone fine.
So my DHD will work with ANY but my sim (which was replaced for a brand new today, with the same line)
And my sim will work with ANY device but my phone.
Oh my head....

Turn Aeroplane mode on, then off continuously until you get a 3G signal. If you still don't get connected, take your battery out, wait 15 minutes, put battery back in and it should connect.
If neither work then I know of nothing more you can do.

If other SIM card works fine and only have issue on 3g, then it must be an operator side error. Go in a TIM store and prove with different SIM cards, and Phone. They have to do someting.

No connection to TMO network (UK) - sim card issue

My phone was not detecting sim card on both. No amount of reboot, wiping fixed this. Was sim card toast? Was the sim card slot a problem?
The T-mobile UK assistance advised putting the simcard into another phone. Fortunately my old phone is still lying around and still works.
Lo and behold, my old phone did detect the simcard and connection to TMO network with 4 bars.
So, was my 2 months old HOX playing up? Transfer simcard back into the HOX, and fired it up. Now simcard recognised and excellent cell connection with 5 bars.
What happened? No idea, and I share this episode in case one of you have a similar problem in future. Lesson: take simcard out and log in to network on a different phone may fix a glitch.

Maybe your SIM card is loose.
Try to remove it and put it in again.
Do you have an original Micro SIM card or did you cut a normal SIM card to fit in the Note 2?

i asked someone to cut my normal sim to micro sim

Maybe he cut the SIM card a little bit too small and so it sometimes looses the contact to the connectors.
Try to remove it and insert it again.
If that doesn't work I would first try to get an original Micro SIM card from your provider before you replace your phone.

ok i will do that. thanks a lot

Unlocked N9750 Dual Sim Mobile Network Connection issues with TMobile SIM installed

Hello,
I just purchased an unlocked Note10+ N9750 Dual Sim in Taiwan, and I am currently located in Taiwan. The phone is on the latest SOFTWARE update from September 1st. ...ASI3.
When I put 2 Taiwanese SIM cards in the phone, the mobile internet works flawlessly and is extremely fast (About 200/50 on each network) when selecting SIM1 or SIM2 for mobile internet, with WiFi disabled. I can switch the cards and it works as expected.
The icons usually show 4G+, although it can sometimes slip into 4G for 10-20 seconds or so.
However, when putting my Tmobile SIM card into SIM1 or SIM2 along with a Taiwanese SIM card, and selecting the Taiwanese SIM card for mobile DATA (The goal here is to use the Taiwanese SIM card for data when in Taiwan), the mobile data is extremely slow (Around 2/0.5).
Furthermore, most of the time, when trying to access the internet, it appears that the phone is trying to connect for the first 5-10 seconds before actually bringing back internet data.
This can be with an app, like Whatsapp, or a simple Google search, or a speed test.
The icons will show 4G+ or 4G, not sure there is a pattern here.
I have tried everything I could think of with roaming ON/OFF, moving the SIM cards around, etc.
APN for Tmobile is correct and setup for IPV4/6 for normal, and IPV4 for roaming.
Again, if I simply replace the Tmobile SIM card with another Taiwanese provider (2 Taiwanese SIM cards installed), the internet is super fast and instantaneous on either SIM card.
The Tmobile SIM is working as expected in a Note9 TMobile Single SIM.
Not sure if anybody has some insight on what may be going on here...
Coming from a Note9 and the Tmobile SIM is less than 1 year old if I recall.
Thank you.

I forgot to mention that if I go into the SIM DEVICE MANAGER with both a Taiwanese SIM card and the TMOBILE SIM card installed and disable the TMOBILE SIM, the internet works fast as expected on the Taiwanese SIM.
As soon as I re-enable the TMOBILE SIM card, the internet is slow again and takes 5-10 seconds before bringing data back from a Google search, etc...

That's because if you are overseas with T-Mobile it caps data speeds I believe at 256kpbs.
I'm guessing the order of the Sim somehow maybe coming into play . Also generally second sim position will give you Lower speeds

Hello Joogle,
I should have mentioned that I have the 15GB pass from Tmobile, so 4G speeds while roaming up to 15GB. The speed when on the Tmobile card is very fast, 50/10 or so.
This is not the issue I believe.
Does 2nd position really give slower speeds? I did not know that.

Interestingly, I am in China at the moment and put a Hong Kong SIM card in slot #2 with my TMOBILE SIM in slot#1. Selected sim#2 for data, and everything works great and is always fast.
Not sure what to make out of that.
Preferred Network is set to: LET/TD-SCDMA/UMTS.
A bit confused by all the options of 4G SWITCHER.

Well, I found out that if I put my TMOBILE SIM in 3G/2G mode only, and leave the Taiwan SIM card at 4G/3G/2G, everything works great and fast with no delay...
This is fine since 3G is good enough for phone calls and text messages.
