I require a sim card for an EWON Cosy 4G EU router and contacted O2 customer service two weeks ago. I was advised by customer service that I can use a regular PAYG sim to transfer code scripts to a machine interface and remote analyze machine operation.
Having purchased the sim card and tried it out the sim card refuses to connect to the internet, the sim card works in my phone but not the machine router. My personal O2 contract sim works in the router perfectly.
Upon contacting O2 customer service again, after an hours hold, being hung up on and looped around different people I was told that you cannot use a PAYG sim in a router.
What sims do I have to use in a router that is not based on a contract?, I see you get dongle sims but I need to be able to send a text message to the sim to wake it up remotely from the Ewon software. Can dongle sims accept text messages?.
Many thanks.
