Hypercard 3G Digital Dualsim Adapter 3G

This item does work once you manage to get everything in order. *However*, I don't suggest using this item with the iPhone 3GS, it got stuck after being inserted and was not easily removed once inserted. I had to dismantle my phone to get the device out. I used one of the micro SIM cutters that are available on Amazon for about $4 and the resulting SIM was still too big to fit in the device. The material that the circuit traces are on is paper thin and easily mangled. After inserting and and fighting to get the device out of my phone the material bent and the surface mount chip ripped off. Word to the wise, this device may work with other cell phones that don't use a small slot and/or tray to load the SIM but it is definitely not something you want to use in your iPhone if you intend to remove it ever once you insert it.

Got the dual sim card adapter last week and tested out. I followed the instruction provided, even though the instruction was not very clear. Cut two of my regualr SIM cards to micro-SIM size using the stickers provided. Put the cards into the dual card adapter. The fit is really tight, and if you are using the metal covers that came with it, make sure that you leave rooms to be able to pull it out later. I really had a hard time getting the adapter out after it was put in the slot.At first, nothing showed up. I had to rebooted for about 5 times and I finally see the STK icon showing up in my app screen. I was really excited and played around with it for about 5 minutes. I then rebooted the phone to see if everything works. But the phone was never able to detect the dual card adapter and the SIMs again.I pulled out both SIMs and put in the regular SIM card adapter and tested the cut SIMs out and they worked perfectly. I guess the adapter must have some problems that my Motorola Photon 4G can only detect it once. What a waste of time and money.

I used this adapter in my Samsung Galaxy S ii using an AT&T sim card and a Movistar sim card from a Mexican cell carrier. It works just great and I am able to change sim cards via an app that came stock on the Galaxy S ii. Both calls, text, and 3G Internet work with both carriers. However, the first few times I tried to cut the cards down, it did not work. The cards have to be cut very precisely, and even then, the entire converter card is too thick to fit smoothly into the sim card slot. So I had to file down the tops of the sim cards to make them thinner, and then it worked fine.UPDATE, December 10th, 2012:After only 9 months of use, this dual sim card adapter failed. It started to go bad slowly, and then finally showed up as a "no sim card" error. I tried both the SAME sim cards in my phone one at a time without the adapter, and both worked. So it is definitely the adapter that went bad.

This team works very well, but the seller must give more information on using the computer. Above all the details of how it works in the part of a telephone that uses only one frequency band. Although both operate without individually but not simultaneously.

my phone keeps me on the go, I like it.

In theory this is a great little product and it certainly does work. I had hoped that it could run both cards simultaneously (which it cannot).It does add an app to the phone (samsung galaxy) that allows you to manage which card is which. I did have to fiddle the cards a little, as it didn't always detect them. Also, unfortunately, because I travel a lot, I did have to change the cards in the sim a few times a year, and eventually it just doesn't work any more. In the end its actually easier to just swap full sized cards - or spend the money on a super cheap second phone - which I eventually did.Great in theory, but loses stars for flimsiness, fiddles, and not quite doing what was needed (running cards simultaneously - which granted is probably as much a phone feature). Easier just to swap cards or have a cheap second phone

I got this adapter as a way to accomodate 2 sims in my ZTE Blade. I found it very difficult to insert the adapter. The software in the adapter did not boot up in the phone. When I tried to take the adapter out of the sim slot, I had great difficulty. Had to try and lever it out with a tweezers as well as gently pulling. It eventually came out, but on the way it dragged out 3 of the 6 nodes that make contact with the sim card. The phone will not now recognise any sim., & will not work. I returned the Adapter to the sender via Amazon. I also emailed the Seller, who is based in Germany. He did not want to know.I have read on another forum that this is a known fault in those type of Adapter. The metal carrier is too thick to fit comfortly in the sim slot. When it dosen't, it is likely to cause trouble. I am very unhappy with my experience of this adapter and the response of the Seller. So my advice is AVOID THIS ADAPTER IF YOU VALUE YOUR PHONE !!!!!

Die Hypercard funktioniert im HTC Desire HD leider nicht so wie ich es mir vorgestellt habe. Die Umschaltzeiten liegen bei ca 60 Sekunden, was ich eindeutig als zu lange empfinde. Laut Verkäufer liegt das aber im Rahmen. Leider klappt das aber auch nicht immer, so dass man dann das Handy neu starten muss. Für diejenigen, die es trotzdem probieren möchten ein kleiner Tipp: Das Einlegen funktioniert relativ mühelos, wenn das obere Abdeckblech weggelassen wird. Mit Blech wird es zum einen sehr eng und zum anderen hat der Adapter die SIM-Karten nicht erkannt. Ich habe mir nun die wesentlich günstigere "MagicSIM Dual SIM Adapter Karte Card Cut (Mit Zuschneiden d. SIM-Karten) 28th-A UMTS/3G/HSDPA/GPS" ebenfalls bei Amazon bestellt. Dieser Adapter ist fast vergleichbar mit der Haypercard, nur wesentlich günstiger. Siehe hierzu auch meine Rezension dort.

Ich nutze eine Geschäftlich / Private TwinBill Karte von Vodaphone (eine SIM, 2 PINs, 2 Telefonnummern) und wollte nun die Hypercard 3G für eine zusätzliche Datenflatrate in meinem Samsung I9000 S nutzen.Da ich wegen der TwinBill Karte unsicher war hatte ich beim Hersteller per Mail vorab angefragt ob dies möglich sei. Ich habe eine Superschnelle und fundierte Antwort erhalten und somit den Adapter gekauft.Ich habe zuerst eine SIM Karte zurechtgeschnitten (was wirklich sehr einfach ist!) um die Funktionsweise zu testen. Also Karte eingesetzt, einen der zwei Metalldeckel aufgesetzt und ins Handy gepakt. Alles hat funktioniert. Also zweite SIM ausgeschnitten... aber dann ließ sich der Deckel nicht mehr vom Adapter entfernen bzw. ist zerbrochen.Mit beiden SIMs lief der Adapter zuerst nicht. Nach Tausch der Slots (der Deckel ließ sich perfekt lösen) läuft jetzt alles Einwandfrei.Mein Samsung schaltet problemlos zwischen beiden Sims um.Den Preis für das Set empfinde ich als deutlich zu hoch, der defekte Deckel ärgert mich. Funktional ist alles Bestens.

Ich habe vor etwa 2 Wochen mir diesen Adapter gekauft. Da ich bei meiner arbeit einige Kollegen die das gleiche Handy wie ich besitze, und Sie diesen Adapter auch in ihren Smartphones haben, habe ich mich auch dazu entschlossen diesen Adapter zu kaufen. Ich habe meine 2 SIM- Karten (Fonic zum telefonieren und Base I.- Flat), zurecht geschnitten, vorab keine Angst, ihr müsst von der Platine Seite auch einiges Wegschnippeln, beeinträchtigt die Funktionalität aber nicht. Habe die SIM's eingelegt und mein Handy gestartet, das 1. mal ging gar nichts, aber nach dem 20.x ging es dann endlich. Ich kann es nur empfehlen finde aber den Preis ein bisschen zu hoch.Nach 4 Monaten, fängt der Adapter an zu spinnen. Das erkennen der SIM Karten kann nicht mehr erfolgen... Habe nach zig versuchen die Hoffnung aufgegeben, und bin wieder auf 1 SIM umgestiegen.Ich bin deshalb sehr enttäuscht, für das Geld hab ich mir mehr Qualität erhofft.
