First of all, the Iphone SE is a phone that was made 5 years after the iphone 4s. Iphone 4s was just not made to support iphone 4s with the provider that you stated. 4g service was released in 2010 by 1 carrier- Sprint. It took a few years for other companies to catch on. Long answer short, the iphone 4s Was Not made to support 4g. Good Luck!
