Common Data Problems and Specific Fixes

Slow Data Speeds:

Network congestion during peak hours, ISP throttling after exceeding data caps, or background apps consuming bandwidth can cause slow speeds. Check your signal strength by measuring dBm values - readings between -50 to -79 dBm indicate excellent signal, while -110 dBm or lower results in no service.

Disable background app refresh for non-essential apps by going to Settings > Apps and limiting background data usage. Consider switching to a different network band or connecting during non-peak hours.

Data Works on Wi-Fi But Not Cellular:

This specifically indicates a mobile network configuration issue rather than an internet or app problem. Verify your APN settings match Consumer Cellular's requirements and ensure mobile data isn't restricted for specific apps in your settings.

Cannot Send/Receive MMS Messages:

MMS requires specific MMSC, MMS proxy, and MMS port settings in your APN configuration. Verify these fields are correctly populated according to your network (AT&T or T-Mobile) and that MMS messaging is enabled in your messaging app settings.

Data Roaming Issues:

If traveling, enable data roaming in Settings > Cellular > Data Roaming (iPhone) or Settings > Network & Internet > Mobile Network > Roaming (Android). Note that international roaming may incur additional charges unless you've enabled International Calling with Consumer Cellular.
