- kogepathic 9y ago> have almost worldwide availability for SIM's designed for this. They are great if you have sensors travelling to different countries or your volume isn't large enough to negotiate with a local telco. If you are deploying many devices in one country it will be far cheaper to talk to a local telco about getting a custoomized data package for your SIM cards. https://eseye.com https://eseye.com is another company supplying these roaming SIM cards.
