) par des modules '4G' dans des applications IoT. L'objectif : recevoir et interprĂȘter des SMS pour agir sur de la domotique en absence de connexion internet. SMS: Quand il s'ait d'Ă©mettre on trouve quelques exemples utilisables (Arduino IDE). Pour ce qui est de recevoir des SMS, je n'ai pas trouvĂ© d'exemples opĂ©rationnels : - les bibliotĂšques usuelles (TinyGSM, 
) ne traitent pas ce sujet; - aucun exemple complet exploitable - semble-t-il - mĂȘme en commandes AT. Lacune qui rend excessivement difficile, sinon impossible l'exploitation de ce module À Ă©carter pour l'instant, le travail de recherche s'avĂ©rant fastidieux et en finale - pour l'instant -improductif. Une immense dĂ©ception qui ne pourra ĂȘtre comblĂ© que quand le fabricant ajoutera dans ses exemples ce genre d'utilisation. [Edit 2023-04-23 :] Pour ceux qui dĂ©sirent une connexion 4G, il vaut mieux envisager les cartes Ă  base de A7670E ou - moins adaptĂ©es A7670A, voire la sĂ©rie des A7600x. En france, il faut privilĂ©gier les cartes offrant les connectivitĂ©s LTE-FDD B3, B20 (4G les plus classiques pour les opĂ©rateurs nationaux). Le LTE-TDD peut ĂȘtre utile si on envisage un usage plus large que l'hexagone. En tous les cas, la consultation des datasheet (site de SIMCom) permet de lever le doute - en particulier sur les bandes de frĂ©quences gĂ©rĂ©es en LTE (→4G) Review: Decent IoT device. Works as advertised and...heh...more... - Let's get one detail straight. The vendor claims that it doesn't work with LTE networks. This is...misleading. If you're talking 4G and 5G? YEAH. It's not capable of anything other than IoT-NB, Cat-M1 (Hint...), and GSM (2G, largely shut down...) for it's connectivity. It's not fast, nor is it intended to be. If your provider does IoT-NB service, this will work nicely. If your provide does LTE Cat-M1 (M2M, narrowband service), it will work nicely as well. The statement that it does not do LTE needs to be dropped by LillyGo- it causes them a problem. It means people won't use their product with a KORE SuperSIM. Which you should rather very much DO. It's using a SIM7000G, _Global_ modem. Works largely worldwide- paired with a KORE SuperSIM, you can have your IOT device work just about anywhere there's, "M2M Cell Service." One proviso. It doesn't do IoT-NB service, the competing answer. If you have one of those providers and an IoT-NB SIM go right on ahead. If you were going to use KORE's SuperSIM or something like Verizon as your provider, go right on ahead with confidence. As long as their M2M service uses Iot-NB OR LTE Cat-M1, you can use this product for your project. That handled and done, how is this as a device. If you can handle the bit of Chonky length introduced by their choice of a 18650 class Lithium rechargeable cell, there's little to NOT like there. ESP32. Development is possible with Arduino, PlatformIO, MicroPython, and more. Fairly high performance dual core microcontroller with 2.5 GHz WiFi, Bluetooth, decent SPI/I2C/GPIO support. Does LTE-M1 data sensibly and...fairly easily...all things considered. SMS is _possible_ but requires your provider _provisioning_ this for you in your SIM for the unit. (Need to have a convo with KORE/Twilio people about the SuperSIM...need SMS directly that simply goes to 1-3 locations, mostly delivering a message to the deistred number as a Mission Critical aspect. Internet's not reliable for this...) Deep Sleep capabilities. Competing devices don't do this right now due to COVID induced supply chain problems. Only real drawback is that, like MOST of the actual plays in IoT, it's less "novice friendly" and has somewhat less than stellar documentation overall- but you'll find yourself thanking yourself down the line for it. It's looking like a solid performer overall to my project- prototype will be able to be done...now that I figured out how the LTE modem actually worked within the device- which is a bit counterintuitive for modems up the Foodchain in the 4G/5G space. ## Features - 16MB Flash and 8M PSRAM - NoteSIM7000G does not support 4G network.

 Sin embargo en la prĂĄctica la documentaciĂłn y los ejemplos de uso no abundan y en cierto modo se ha quedado obsoleta. Si la piensas usar para MQTT sobre TLS, es un verdadero infierno. Recomiendo comprar la versiĂłn que lleva una TSIM 7600, con un juego de comandos AT mayor. ## Frequently Bought Together - LILYGO T-SIM7000G ESP32-WROVER-B Solar Charge SIM GPS Antenna CH9102F 16MB 2G/NB TTGO Development Board - Soracom Air Global Plan01s IoT SIM Card Secure Cellular Connectivity SIM Card for IoT M2M Projects Pay as You Go No Contract (1-Pack) --- ## 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.pe/products/498465668-lilygo-solar-charge-development-board-module-esp32-wrover-b-wifi](https://www.desertcart.pe/products/498465668-lilygo-solar-charge-development-board-module-esp32-wrover-b-wifi) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-06-01*
