If you´re looking for a reliable and price affordable connectors for memory cards and SIM cards, we have a solution for you.
No doubt, that data storage media and SIM cards need a reliable contact. A contact which won´t oxidize either after a long term usage in an outdoor environment. This fact is well known mainly to producers of outdoor operating devices, often in outlying localities, where every servicing causes useless expenses.
That´s why, in our offer can be found several connectors and holders of a quality construction from company Attend with an excellent price / performance ratio. Some connectors from company Attend may be familiar to you for example also from our article Migrate to a new type of a SIM card connector Attend. We gradually increased number of types held in stock and recently we also added another 2 types – holder for two SIM cards 115H-BA00 and holder for Micro SIM 115I-BEAA. Attend connectors feature gold-plated contacts and they´re specified for industrial temperature range. All details necessary for usage of these connectors can be found in datasheets at particular types.
In case of interest in any Attend component, please contact us at email@example.com.

All in one GSM 3G module Quectel U10 simplifies schematics and shortens testing time thanks to a quantum of built-in interfaces. If you´re searching for a module for transfer of data, voice, video, SMS and MMS, which has everything imaginable already built-in, then the Quectel U10 is the right solution for you.
Unbelievably many functions, supported protocols, built-in interfaces and other features are provided by the new 3G module Quectel U10. Thanks to this, in the most of applications it isn´t necessary to connect any other interfaces, what decreases the production cost of a target device. Only the list of features itself would occupy the whole article, that´s why we will mention at least some of them.
The module supports dual mode and is multi-band (WCDMA & GSM) and a UMTS (HSPA) high-speed data transfer, further supported even by a high-speed USB 2.0 interface and three UART channels. CMOS camera interface with an 8 Mpx resolution enables a direct camera connection without other extra costs. All necessary can be stored into a directly connectable SD card with up to 32 GB capacity. To gain a Bluetooth communication, it is only necessary to connect an antenna to the U10. The U10 module also contains a control circuit for Li-ion battery charging, what is convenient in mobile applications, as well as when using a battery as a backup source. RIL (radio interface layer) driver for WinCE6.0 and a USB driver for WinCE 6.0, Win7/XP and Linux 2.6 further simplify a communication and connectivity. Excellent sensitivity, advanced audio algorithms and video codecs contribute to universal usage of the U10 module. So that it was possible to use all functions without limitations, a given circuit should have a wide operating temperature range – U10 meets even this requirement at 100% and has a guaranteed functionality in range from -40 to +85°C. Connection of the U10 to a PCB is very simple, by an SMD connector (board to board). The module naturally enables to use SIM cards of any GSM operator. U10EVB-KIT development kit is also available for a development support.
Basic information will provide you the U10 module specification and the Quectel U10 presentation. Detailed information will provide you the U10 Hardware Design, U10 AT Commands set, U10 EVB kit user guide and the video call application note.
U10, as well as U10-EVB kit are available directly from our stock. Guide price of the U10 module is 50 EUR at purchase of 1 pcs. Upon request we´ll let you know the exact price for your project.

New version of Attend connectors for SIM cards replaces the current one. To make it to you easier, we will keep in stock both types for some time.
It is the six-pin „push-push“ type 115A-ADA0-R02, which will replace the older almost identical type 115A-ADA0-R01. New type differs from the older one only in the width and a position of side mounting lugs, which are soldered on a PCB. Lugs of the new type are somewhat closer to the middle of the connector and they are narrower. The difference is probably best illustrated at the enclosed pictures. Both types also contain a switch for SIM card detection. Detailed information will provide you the 115A-ADA0-R02 and 115A-ADA0-R01 datasheets.

McZ found a sim card power supply with level translator:
The TXS4555 is a complete Smart Identity Module (SIM) card solution for interfacing wireless baseband processors with a SIM card to store I/O for mobile handset applications. The device complies with ISO/IEC Smart-Card Interface requirements as well as GSM and 3G mobile standards. It includes a high-speed level translator capable of supporting Class-B (2.95 V) and Class-C (1.8 V) interfaces, a low-dropout (LDO) voltage regulator that has output voltages that are selectable between 2.95-V Class-B and 1.8-V Class-C interfaces.

This project details how to build a Smart/SIM card reader/writer for experimentation and investigation of SIM & Smart cards. Once the reader design is built, the open source software can be used to read from and write to the card. Together they can be used to backup/restore stored SIM card data, recover deleted SMS’s and phone contacts, examine the last phone numbers dialed, etc.
