I have given it a 3 Stars not for the product but the support, the product gets 5 but the support gets 1 hence the 3 !! I'm not using PI or Raspberry so don't ask for help with those I design my own boards and hand shake between sim modules and PIC devices. ### ⭐⭐⭐⭐ Needs twisted serial port wires if not plugged directly onto the Raspberry Pi *by D***. on 7 February 2021* It took me a long time to get this working reliably with my Raspberry Pi.When plugged directly onto the Pi it worked but was unreliable which I beleive was due to current limitations. I then unplugged from the and wired it up next to the Pi (this actually suited me as I wanted to git another HAT anyway).The Rx/Tx lines were only 75mm long but the communication was extremely unreliable. One day it would work but another day and I couldn't get a response from the AT command. After I twisted the Rx/Tx wires and the communication became 100% reliable.So, in summary, for best reliability, I found that it worked better if not plugged into the Pi, decent 5V supply direct to the board and twisted Rx/Tx wires. ### ⭐⭐⭐ Needs a bit of tinkering *by A***N on 28 December 2020* Needs a fair bit of tinkering to get it to workMost importantFeeding the power to the board not through the pi increased reliability with network connectivity ## Frequently Bought Together - GSM/GPRS/Bluetooth HAT for Raspberry Pi 3B+/3B/2B/Zero/Zero W Based on SIM800C, Allow Pi to Send Messages, Connect to Wireless Internet, Transfer Data via Bluetooth, UART Interface - Raspberry Pi Zero 2W - Raspberry Pi 5 (8GB) --- ## 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.co.uk/products/132218596-gsm-gprs-bluetooth-hat-for-raspberry-pi-3b-3b-2b](https://www.desertcart.co.uk/products/132218596-gsm-gprs-bluetooth-hat-for-raspberry-pi-3b-3b-2b) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
