Verizon, T-Mobile and AT&T are all withdrawing their buy-one, get-one offers on some of the market’s top smartphones, an action that reflects the relatively benign competitive environment in the wireless industry.

However, some industry experts believe this is just the lull before the storm, and that operators may engage in significant competitive promotions around devices like the iPhone XR during the critical fourth-quarter holiday shopping season, which typically kicks off during Thanksgiving.

“T-Mobile and Verizon in late September pulled their BOGO offers, AT&T has added TV/Internet requirements to its BOGO, and Sprint has raised Galaxy switcher pricing while easing up on Kickstart and ‘flash sale’ offers,” wrote Wave7 Research, an analyst firm that closely tracks promotions by wireless network operators. “Wave7 Research believes that this is likely not a secular trend, just a lull between the iPhone XS launch on 9/21 and the iPhone XR launch on 10/26.”
