“We had to remove signal strength from CarrierCompare to remain in compliance with our developer agreement with Apple and avoid having our apps pulled from the App Store entirely. Apple has been very cooperative through this process, and we are pursuing ways of bringing signal strength back in the future.
As mentioned in the CarrierCompare update description, signal strength has the smallest impact on the quality of your data experience, so the rankings we present will continue to focus on that. We recognize signal strength is an important metric for comparing voice quality, and we encourage you to mention it in your reviews and emails to us if it’s particularly important to you.”
How odd, a company being judged can have results pulled! Is one radio better than another?
