I've been buying cheap combo 4G/wifi routers that contain Sim card slots, setting the router up as usual, and then connecting the esp32 to the router's wifi network. So far it's been a more stable solution than any standalone microcontroller / module I've used, and easier to replace with local parts if anything happens.
- alex_sf 4y agoThat's clever. Have you had good luck with a particular model?
- jareklupinski 4y agohaven't had any major issues post-deployment with any of the random amzn/aliexpress ones I've used so far, fingers crossed i've noticed that if your phone doesnt get full signal in the spot you want to place the router at all times of the day, a cheaper router usually doesnt stand a chance of getting a good signal without an external antenna the ones where you can attach an external antenna with a wire lead are usually easier to position in just the right spot for full bars, and they just seem 'hardier' of the bunch, but you need the antenna, tradeoffs
