T-Mobile in US followed some aggressive tactics for months to entice customers using other network carriers. Also, the country’s second largest operator AT&T was not one to be left behind as it offered to pay its customers handsomely for switching to AT&T to T-Mobile. Following this, Sprint Corp, ranked 3rd in the US, started offering heavy discounts on friend and family groups. T-Mobile took the battle one step further by announcing that it would be paying an astronomical exit cost to all those who convert to T-Mobile. Aggressive marketing done by AT&T and Sprint come on the heels of the recent steps taken by T-Mobile, an industry dawdler for a long time, reported customer growth of three full quarters after it faced losses for four consecutive years.
