He removes the SIM card from the free telephone acquired and inserts SIM card into GSM PBX, making the system totally functional. Now he can talk to GSM PBX free of charge as much as he wants anytime (subscriber to subscriber call within the same calling plan). GSM PBX now dials all his calls via the low-cost home landline, so Steve experiences a pointy lower within the number of paid AT&T™ minutes used. He can now change to a plan with less minutes to avoid wasting even more." GSM PBX is available from www.mobileactivator.com
