Operating at 3.7~4.2V with ultra-low power consumption (1mA in sleep mode), it supports voice calls, SMS, GPRS data transmission, and FM radio. Featuring a UART TTL serial interface with auto baud detection, it easily integrates with popular microcontrollers like Arduino and Raspberry Pi, making it an ideal choice for professional IoT and remote communication projects. ## Description Description: Mini GSM / GPRS breakout board is based on SIM800L module, supports quad-band GSM/GPRS network, available for GPRS and SMS message data remote transmission. The board features compact size and low current consumption. With power saving technique, the current consumption is as low as 1mA in sleep mode. It communicates with microcontroller via UART port, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands. Working Voltage: 3.5~4.2V Quad-band 850/900/1800/1900MHz Connect onto any global GSM network with any 2G SIM Make and receive voice calls using a headset or an external 8 speaker and electret microphone. Send and receive SMS messages. Send and receive GPRS data (TCP/IP, HTTP, etc.) . Scan and receive FM radio broadcasts. Lead out buzzer and vibrational motor control port. AT command interface with "auto baud" detection. Package Included:1*SIM800L GPRS GSM Breakout Module Review: Works great dont listen to the people who say it wont work. - Works great! Used a dc to dc buck converter to regulate to 4.4 volts, and a micro pro to drive it. Make sure you have tmobile or else 2g wont work in the usa. All other carriers do not work as they dropped 2g networks. 2g support for tmobile will be dropped December 31st 2020 so after that this will not work.. Review: Relatively old cell phone technology, but works great - This was my first-ever GPRS GSM board. Note that you'll need a SIM card and cell phone service. Note that if you are interested in medium-distance communication, that LoRa may be a useful alternative which does not require cellular service or a SIM card. The card needed is the "Mini" SIM, smaller than the full size, old school SIMs, and larger than the MicroSIMs (although most Micro Sims come with adapters) At least one reviewer claimed to receive a humidity sensor. I can confirm mine was actually a GPRS GSM board, just as pictured. As with many devices, Adafruit has an excellent online tutorial to help get started. Note that Adafruit stated that "In the US, AT&T no longer sells 2G SIMs! We suggest T-Mobile or T-Mobile distributors", As well as: "The 'H differs from the 'L in supporting bluetooth and fax. Otherwise its the same". There's also no text to speech on the L version. In short, this is an excellent, low-cost board to be introduced to the world of GPRS GSM communications ## Features - Mini GSM / GPRS breakout board is based on SIM800L module, supports quad-band GSM/GPRS network, available for GPRS and SMS message data remote transmission. - The board features compact size and low current consumption.

I'm having trouble attaching to the network. (The sim was recognized)** A: Yes, it should work if properly configured **Q: ¿Does this product supports ussd codes?** A: YES... but remember that USSD, SMS etc. are protocols and therefore will require specialized parsing of incoming data as well as the protocol specific structure of outgoing data... I have seen 'some' sample USSD samples in the Arduino world... I am not aware of any LIBARIES... Also I have not actually worked with this protocol myself in the IoT environment. Know that MOST ALL cell phones (chipsets) that are GSM specification will support the USSD protocol. **Q: Is this G3 compatible?** A: Do you mean 3G compatible. The device is not, the Hologram SIM is ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great dont listen to the people who say it wont work. *by B***R on February 22, 2020* Works great!

We kept receiving an error that the SIM card wasn't there. Searches on the internet and Amazon blamed the modules as being faulty and said you can order 10 and find 4 good ones. We eventually found out that we were inserting the SIM card in backwards..... OOPS! Flipped them around and everything was good. Module seems to be pretty good for the price ## Frequently Bought Together - HiLetgo Smallest SIM800L GPRS GSM Breakout Module Quad-Band 850/900/1800/1900MHz SIM Card Slot Onboard with Antenna 3.7~4.2V - Teyleten Robot ATGM336H GPS+BDS Dual-Mode Module Flight Control Satellite Positioning Navigator Replacement NEO-M8N NEO-6M for Arduino 2pcs - 2pcs ESP32-DevKitC core Board ESP32 Development Board ESP32-WROOM-32U WiFi Bluetooth Development Board for Arduino IDE (WROOM-32U) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/26587866-hiletgo-smallest-sim800l-gprs-gsm-breakout-module-quad-band-850](https://www.desertcart.tn/products/26587866-hiletgo-smallest-sim800l-gprs-gsm-breakout-module-quad-band-850) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-12*
