This event of the Gsm led flashing red occurs only when the device is turned on. When turned on, the Gsm led flashes red, then starts flashing green, and then turns off. When the Gsm led turns off, the device is ready for use.
If after several seconds from turning on the Gsm led continues to flash red, you must check some things, as the device has an anomalous behavior:
Is the sim present in the device? Check
Is the inserted sim of the required type? It must be a micro sim
Has the sima been correctly inserted as reported in the instructions and as also drawn on the case of the device next to where it should be inserted? Attention! When inserted, the sim should make a click and remain inserted, and the relative cut of the same should be visible on the outside
Have you removed the sim pin? Check by putting the sim inside a cell phone for the presence of a possible pin and remove it if necessary.
