Dual SIM Adapter

Hi,
has anyone successfully used a dual sim adapter with the LG E900 Optimus 7 ?
I am looking to buy this phone but need the dual sim.
thanks for your help and replies.
Yea i've used one of these before with a MagicSim 28th gen cut.

I'm very interested on the matter, could you please let me know how you can switch from one sim to the other with the LG Optimus 7.
Do you have a dedicated WP7 application to install or the phone automatically detects the dual sim adapter?
Please let me know.
Thanks.
hjkl;' why no delete?
Send me a PM and i'll point you to where i get mine from.
Having a lot of private messages asking where i get it from so i'll put it here.
"directdevices" on ebay. The cutting version isn't listed but if you message them they have them in stock
Hope this helps everyone!
Can you tell me please, how you switch between the sim cards. Because I have the Magicsim 28th but I can't switch between the SIM cards.
Thank you
Have you found the stk (sim tool kit) menu?
No i didn't find the STK menu.
I thought Windows Phone 7 don't has a STK ?
What's the deal with this? Looking for a dual sim adapter for my girlfriend who has this phone.
Did it work out ok?
I can confirm that the Magicsim 28th gen PLUS works on this phone for anyone thats interested.
Got it from www.magic-sim.com
I've had 2 off them now for a couple of different phones and i'm dead pleased.

Thank you very much Daniel
Hi I got the Adapter for my HD7 Pro and i cant find the stk menu.
Can anybody tell me where it is, or tell me how to change the sim.
I requestet support from the vendor but they say if i cant find the stk, i should have to change to android ?! wtf
Please help
They may be right....what firmware you running?
I run the firmwareversion: 2250.21.30201.207
an mango: 7.10.7720.68
Yea I'd guess they're probably right. From my understanding some newer windows versions have stopped supporting stk.
Your best bet is getting over to android as it works real well on my setup. I'm on 2.3.5 if that helps?
Good luck.
OK, i think i try another Adapter, this time a analog one, maybe this works
Thank you for your fast support
No probs... Although I'd be aware that no dual sim adapter will work without an stk menu. So your only real option is to change firmware if you want dual sim capabilities.

[Q] Galaxy tab damages SIM card!!!

I used my tablet (Galaxy tab 10.1 P7500) with wifi only for almost 1 year. Recently I bought a SIM card (regular, not mini SIM) for using 3G with my tablet. It worked for about 10 days and then stopped working. Surprisingly, when I took the SIM out and tried to use with a phone, the SIM failed to register with the network! My operator told me that the SIM has been probably damaged and replaced it with another. In another 10 days I am facing the same problem again!
I wish to make these clear:
- I inserted the SIM properly into the tablet as per the instructions. I had not removed it thereafter. So, there is no probability of damage.
- In both the instances, the SIM looked perfectly all right. Not even a scratch!
- My operator swears that the problem is with the tablet and it does something to the SIM and makes it non-functional.
My questions:
1) What is the possible reason behind this?
2) Can the tablet work with a regular SIM?
3) Can the tablet damage a regular SIM with 10 days of use?
4) Should I use a micro SIM?
5) Will the problem recur with a micro SIM?
Any help will be highly appreciated! Thanks!
what I did when got the same problem

1)dust or movement of the card
You can use only the same size of sim as you had, the size doesn't matter, it just need to "seat" right
Try: buy a fresh new eraser for the old school pencils and gently clean the SIM card - only a new eraser so you won't damage it, don't push too hard, this way you remove any small parts on it that could block it.
Eject your SIM card only when the system is shut down. and restore it in shutdown mode again.
Be sure you turn your wifi off before shuting down so you could initialize the sim at boot and see if you got conection.
Good Luck.

How does Dual Sim work?

Hey guys
Before hitting buy on one of these, can someone please explain to me how dual sim works? Preferably with some screenshots. This is going to be my first dual-sim phone
I understand dual sim dual standby, in that both sims can use 3G/4G but only one at a time. Do you decide which SIM is the main active one for data in software?
Thanks
Ive got the prime
I can choose Internet from sim 1 and call from sim 2

Dual Sim not working - Wileyfox Swift 2x

Hi,
Just picked up a Wileyfox swift 2x and am having an issue using it in dual sim mode.
When a single sim is enabled it works just fine but when the second sim is enabled that sim does not connect to the network, if I disable the original sim the second sim then receives reception as normal.
Have looked on the forums but cannot see any other users having the same issue so don't know how to progress this.
Have used these sims in a dual sim phone previously without any issue so its clearly a handset rather than an operator issue.
Any help appreciated!

Ended up returning the phone and replacement handset worked fine so issue was phone specific.

Sim card on chinese android

Hi everyone,
I had been using a phone Huawei Y635 (rooted, RR 5.8.4) for several days with my mobile operator (Vodafone), surfing in 3g and 4g with no problems, when yesterday I had to insert another mobile operator sim card (3 Italia, which is based on UMTS system) and the phone didn’t detect it.
So I did some tests that I will list below:
1. I inserted the same 3 sim card in another phone (Lumia 925) and it worked perfectly;
2. I tried a second 3 sim card – that usually works in a Samsung A5 – and, again, the Y635 didn’t detect it;
3. I did a counter-check by inserting another mobile operator sim card (Tim) in the Huawei Y635 e this one had been detected at the first shot.
4. I checked the sim cards were well inserted in their lodgings and I also tried to use both the sim slots (it’s a dual sim phone), but nothing changed.
5. Finally, I went to a 3 Center, and you can imagine what kind of assistance those girls could have given to me...
I know that some Chinese phones had problems with 3 operator, such us IMEI problems, etc., but I understood it’s a problem that shows only in terminals which set Mediatek processors.
The Y635 has a Snapdragon processor. I don’t remember the code, but it’s not Mediatek.
Do you have any idea about it?
anyone can help me?
