“Mark L. was a great help! He called me with plenty of notice to let me know he was running a little late on his previous installment, which most companies will not do. Then he called to let me know he was on his way, also something I haven't seen with other companies. He explained everything he was checking & what he was switching out or fixing. He let me know what the problem was and reassured me that it would be taken care of today. He also noticed that when it was fixed, the speeds weren't exactly where they needed to be yet so he got it all straightened out before finishing up the job. I really appreciate being informed & someone taking the extra step for a customer to have the best Internet performance. By far, the best customer service out of any provider I've had.”

“We recently visited one of the corporate Verizon stores in Sioux Falls and upgraded from the Pixel 7 Pro XL to the Pixel 10 Pro XL. The phones were not in stock and were shipped to our home address. Because of where we live, we were advised that we could take the phones to the Sunnybrook corporate Verizon store in Sioux City, IA to have the data transferred from our old phones to the new ones. Today (02.24.2026) we went to the corporate store as advised. The gentleman who helped us was knowledgeable, helpful, and got everything transferred with no problems and in a timely manner. He also installed our screen protectors and cases. We were very appreciative and pleased with the service we received today and highly recommend this store and the gentleman who helped us. Sadly, we did not get his name.”
