A:AnswerYes, you can use it in Mexico but is there is not 5G there is going to work with 4G LTE, 3G or 2G all depends on what Data bands are available there.
A:AnswerYou can get unlocked phones with cricket and they will work. I had a s20 and my boyfriend has the note 20 ultra both worked unlocked.
But just know as of right now they have the 5g locked and it can only be used with their 5g phone. So you won't be able to use 5g right now with cricket but the phone the phone itself you can use.
A:AnswerThe phone should auto adjust on its own but you can always use a 4g sim card which will prohibit the 5G network. I just let it auto adjust though and have no issues
A:AnswerIt has Bluetooth connectivity, so it can connect to wireless devices. I am not sure what is used to connect with hearing aids. It does not have a 3.5mm headphone jack however, I was quite surprised to discover.
A:AnswerYes, it's the same slot as the SIM card. SIM card goes on one side, sd card goes on the other. I have a 256GB sd card in mine for pictures and videos.
A:Answerif your network provider or your internet service provider offers 5g, it should be turned on by default. make sure that you confirm in the settings that 5g is indeed enabled.
A:Answeryes it can, it comes with a built in mic. you dont need a headphone jack. it works for zooms meetings. just go to the google play store and download "zoom" then you should be all set!
A:AnswerIt should work with straight talk. I have google fi so I'm not totally sure but if you go on the straight talk website there actually selling the s20 fe so it's safe to assume that this phone does work on your carrier.
