Hi there! @saxygirl Thanks for posting your concerns.
I’m sorry to hear you’re having sluggish speeds on your iPhone. There are a few things you can do to clear that. The first is, turn the phone off for 2-3 minutes. This will allow the phone to re-register with the data network and should help.
If you continue to have slow connectivity, try performing a network reset. You will not lose information, however, you may need to re-enter any secure Wi-Fi network keys you use on a regular basis. Please go to settings>general>reset>reset network settings. The phone will turn off and back on.
Thanks!
Charise
