Please add more information 

Hello @MadnessOfMarch, we understand the importance of being able to make and receive calls. We're happy to help with troubleshooting steps to help resolve your concerns. 

Thank you. @formerlyknownas for the prompt response. In addition, we recommend checking if the HD Voice feature is turned on.

If you can’t make or receive calls, or you’re having trouble accessing data, check the VoLTE or LTE status of your phone, and walk through the below troubleshooting steps: 

• Go to Settings, then Connection. Choose Mobile networks, then Enhanced LTE services, and select On.
• Check to make sure that your device will work on the AT&T Network by entering your IMEI on our device identification page.
• Make sure that the device software is up to date to get the latest device software to make sure you have the latest features and device protection options.

In these instances, we also recommened visiting our Wireless call troubleshooting help page for step by step solutions. Start by signing into your myAT&T account, and then select the Make and Model of your device then follow the prompts. 

Meet us back here with the results of the troubleshooting tool if you still have questions, and we'll be happy to walk through additional troubleshooting options. Thank you for contacting AT&T Communtiy Forums.

Went to Settings, then Network & Internet, clicked mobile network, lists:

Mobile data (on)

International data roaming (off)

Data usage

Allow 2G service (off)

Mobile Network Dianostics (on)

Automatically select network (on)

Network

Access Point Names

And I already made sure the software was updated on the phone.

And yet your phone indicates it has no service. To me this means either you never activated SIM card or the SIM card you did have is no longer functioning. This may be because you haven't paid for service, have not refilled your service, the SIM card could be damaged, your phone number could have been ported to a different service provider.  Or your service could have been canceled because you haven't refilled on time. 

Your information is insufficient to sort out exactly what your problem is. ATT help has assumed that you do have active service.   

Clearly you do not if the phone says no service. 🚫

We'd be more than happy to step in to help with connectivity for your Fusion Z device, @MadnessOfMarch

Special thanks to our ACE, @formerlyknownas, for their quick response. We just have a few quick questions.

- Did you purchase this device through us or 3rd party?

- Was your device unlocked or locked at the time of purchase?

- When was the last time you changed out your SIM card?

- Do you have wireless services with us currently?

We're asking because we want to pinpoint what could be impacting the ability for your device to connect to our network.

In the meantime, our first recommendation would be to double-check if your unlocked device can connect to our network. It appears that an unlocked Fusion Z is not compatible on our network.

Our second recommendation would be to order a replacement SIM card.  Typically, SIM cards collect dust and debris overtime. This can sometimes interfere with cellular signals. You can get SIM card kits at one of our stores, online through att.com, or from another online retailer. The kits come with three SIM card sizes. You can use it if you want to bring your own device to AT&T, or if you just need a new physical SIM.

Our third recommendation would be to activate your device. Many devices use a physical SIM card that is already inserted in the device. If you use a different SIM, you might not be able to access our wireless network or use all our network features.

If your SIM isn’t already inserted, learn how to put it in.

1. Go to https://www.att.com/device-support/index/9004941.

2. Choose your device.

3. Scroll to Getting started and select Hardware & phone details.

4. Choose Insert or remove SIM card and follow the steps.

Please let us know if this helps, and we can continue offering support. Thanks for reaching out to AT&T Community Forums!

- Did you purchase this device through us or 3rd party?

We received it from AT&T as a replacement for a 3G phone.

- Was your device unlocked or locked at the time of purchase?

Locked.

- When was the last time you changed out your SIM card?

AT&T sent wrong SIM card when we first got new phone, and they sent a replacement SIM card, and that has been the SIM card for that phone ever since. This phone had been able to accept/make text/calls in the past. 

- Do you have wireless services with us currently?

Yes! We have been a AT&T customer for better than 20 years.

And YES @formerlyknownas , the account has been in excellent standing and properly paid for every month. Do not appreciate, not once, but twice, you suggesting the problem is we are not paying for the service. Since you do not work for AT&T, unless you have something positive to say to help with the problem, please keep your opinions to yourself, thank you.
