tor’s APN address. Change APN address if necessary. Other modem settings can normally stay as they are. If factory
settings are for some reason lost, they can be restored (see page 3).

If you enable Wi-Fi connectivity, you need to put Wi-
Fi antennas (1-2 pcs) into the modem. The wireless
network does not work without external antennas,
as there is no built-in antenna in the modem. The
antennas are not included in the 3G-MOD4 package,
but you can purchase them from Ouman.
