The OnePlus 7 Pro will eventually make its way to the market in a few days and comes with a slew of impressive features, including a 90Hz display, an in-display fingerprint scanner, a triple camera system and more. Then again, what good are those features unless the phone cannot perform one of its most primary functions, which is making a call. To see how OnePlus’ latest phone compares with the Samsung Galaxy S10, and last year’s iPhone XS Max, and LG V40 in terms of signal strength, PCMag and Cellular Insights recently put the phones to test, with the results provided below.

When it comes to cellular reception, all phones are not created equal and their performance has a lot to do with the frequency bands that are supported by their modems as well as the antenna. Although both the OnePlus 7 Pro and Galaxy S10 pack in Qualcomm’s X24 modem, the latter supports 7-carrier aggregation which gives it theoretical speeds of up to 2Gbps, while the former includes 5-carrier aggregation and theoretical speeds as high as 1.2Gbps.
