Was on an old plan and upgraded to 5G a few months ago. If I'm outside it works fine but as soon as I go inside a building, any building anywhere, it drops back to 4G and says I have no internet connection. I have to go outside to reliably use my phone to get online. Text and calling work fine inside but no internet connection. Powering off and on, resetting the network settings, taking out the SIM card etc have done nothing to resolve the issue. Went to the cricket store and they told me to call customer support. Called customer support twice and talked to two different people who told me to do the things listed above, which proved ineffective. Said they'd call me back but never did. Seems like the only solution is to switch to a different carrier. I don't know what else I'm supposed to do.
