Why won't my sdhc card work in my zte atrium cell phone?

I had a regular memory card that wouldn’t work in my phone. Looked online and discovered that I needed a sdhc card. I got a 16 GB sdhc card and it won’t work either. I’m frustrated. Please help!

I would think your question would be better directed to your phone manufacturer. Do they have a support page on their website or a user’s forum where you can search or ask your questions there?
