I am hearing impaired and want to find a phone which is hearing aid compatible. Would you recommend this phone?

I would think that if you called them and asked if your current phone is compatible they would be able to tell you.

That being said, they have a page showing Hearing Aid compatible phones they provide and might give you an indication of whether your phone will work with their service:

Further research also reveals that they support/use both CDMA and GSM networks which means you should be able to use just about any modern phone with them.

Only when your hearing aid has bluetooth, you could be able to connect it to a smart phone. But the manual that came with the hearing aid, should mention what systems are compatible with the hearing aid. Like iOS (Apple), Android or Windows (Microsoft)
Then the manual also will say what app you have to install and how to get it.
Pairing, goes with switching on bluetooth and most of the time you have to enter a code to allow the systems to pair. The code for your hearing aid should be in the manual.

Hello,

Your phone might be configured to automatically adjust according to timezones. Try to refer to the instructions manual to have this corrected
