What may be the problem is that the dongle settings aren’t on RSAWEB.
If you boot up the laptop with the dongle in, when you open the browser a Heuwei admin screen will open with a username of both Admin (or admin) password settings are there. If you access please double check that the apn settings are set to rsaweb.mobi
If this doesn’t work please log an call with RSAWeb on 087 470 0000 or [email protected] so they can troubleshoot the matter with you personally. Please see that you have the SIM number handy.
