MUDI + AT&T in USA

I heard Mudi doesn’t work with AT&T in USA now. When can it be fixed?

2

Did anyone tried Mudi + AT&T in USA?

3

I’m on an AT&T MVNO and I have successfully connected. I’m currently only getting 3g service, I think that’s probably a frequency availability issue with the Mudi. I tried to manually configure the APN, reset the modem…didn’t seem to work. Then I put in an inactive secondary APN that I found on my phone, reset…didn’t seem to work. I then put in my cellphone number into the manual configuration and hit auto configure and reset. A few minutes later, I was connected. Not exactly sure which one of those worked…

I also got 3G working on AT&T. but we need LTE working, correct?

5

Can you make sure you got an American version? The UI shows the model of the modem. Can you give a screenshot?

If you used a version not for the US you will get 3G network.

by the way, with the above settings, I still don’t get data connection to AT&T (even 3G). The sim card works (it is a unlimited iPad plan sim card by AT&T, not a MVNO card)

If possible, can I help you remotely?

9

Yes. That will be great! How can I setup the Mudi to get your remote troubleshooting?

It seems that your APN is not correct, the Nighthawk MR1100 use this APN:

but it shows ‘3G’, which means the U.S. version of MUDI, with EC25AFF doesn’t event have the right band for AT&T, correct?

12

by the way, by changing the APN to ‘broadband’ and reboot. AT&T works now! Thanks!

13

Showing 3G does not mean it does not have the right band.

Glad to know!

I wrote a post here where you can follow the steps and try to solve the problem

15

Are you getting AT&T LTE service now?

16

Has anyone had any luck with the EP06A?(EP06ALAR02A07M4G), shows 3g with no connection(apn set to broadband). This same card works fine with lte in my nighthawk.

17

Yes. I confirmed EP06A works (I bought a US version of MUDI with EC25AF, then I swap it using a EP06A).

You just need to follow the instruction above. device is /dev/cdc-wdm0, APN to ‘broadband’

then reboot.

it worked for me.

Have you tried the method in the link? AT&T (ATT) network fix

step two doesn’t target the ep06a, R02 is the version string on it. R05/07 are what the second part of those instructions are for. @ken555 I have had it set to broadband since I got it. No dice.
