The tug-of-war for subscribers among United States wireless companies has intensified, with Sprint now offering $200 for customers to return to the service after switching to another carrier.

Sprint is already offering $650 for customers to switch to the carrier from Sprint's rival companies, including AT&T, Verizon and T-Mobile. The amount will be used to cover the costs associated with switching carriers such as early termination fees.

Earlier in the year, Sprint even started a 30-day satisfaction guarantee for customers switching to the carrier. Customers who sign up for a Sprint contract but are not impressed with the service that they receive are allowed to have the cost of their device, along with all the associated service charges, refunded after returning the device to the company.

Sprint, on top of all its carrier switch deals, is now also offering customers who return to the company after being enticed to move to another carrier with $200 worth of credit that can be applied to the cost of their service.

The promotion is set to run until mid-September, and can be used in conjunction with the $650 offer for customers switching from other carriers. In total, returning Sprint customers can get up to $850 if they choose to return to the company's services.

Sprint is currently behind its rivals in terms of the number of its subscribers, and the company is hoping that through these offers and heavy marketing, it would be able to acquire a larger share of the cutthroat wireless carrier market.

One of the recent moves that Sprint made involves Paul Marcarelli, the guy featured in Verizon advertisements that ran from 2002 to 2011 with the infamous tagline "Can you hear me now" to check the signal of the service. Marcarelli, like what the company is hoping with a significant number of subscribers, has made the switch to Sprint.

Marcarelli, in his first advertisements for Sprint, explained that every network is now great, adding that the reliability of the services of Sprint are within 1 percent to that of Verizon's, but with lower rates compared to what Verizon offers to customers.

Sprint reported 173,000 new postpaid subscribers for the last quarter, revealing hefty growth for the company. However, despite that, the company still posted a significant loss of $302 million for its fiscal first quarter, equivalent to a loss of 8 cents per share. This is compared to a $20 million loss in the corresponding quarter of 2015, equivalent to a loss of 1 cent per share.
