MobileMustHave Wireless direct data plans:

  • B300 Plan/B800 Plan



If you are interested in using your Pepwave modem on MMH Wireless B800 Cellular Data Plan (formerly B300), some settings may need to be changed to have the modem negotiate with these networks. Typically selecting "AT&T" or leaving your modem on "auto" under carrier selection will allow the unit to connect however manually setting the APN is strongly advised to ensure the top performance of your plan and faster connection times.

Entering the Custom APN

Navigate to the Dashboard tab and select the cellular details button of the modem you wish to add this data plan to. 

Click the cellular details button of the cellular modem you wish to change

Scroll down Cellular Settings, select Custom under Operator Settings. Make sure to select the proper SLOT A or B based on where your MMH B800 is located. Change the section corresponding with the correct sim card

This will enable the APN box where you can enter the APN information. For the MMH Wireless plan the APN you need to enter "broadband" entered without the quotes as shown in the image below.  


As shown in the screenshot above. We recommend also setting the LTE/3G network selection box to LTE as the 3G network has been disabled by AT&T as of February 22, 2022. 

(Optional) Bandwidth Allowance Monitoring

This step is optional, but if you would also like to set up bandwidth monitoring to automatically shut off your plan before you go over your usage, you can use the screenshot above as guidance.  The data will reset on the 16th for everyone and it is suggested to shut off 750 so you know you have 50GB left of emergency data. The B800 will likely work over 800GB, but is contracted to work for 800GB so setting this is a safe bet to give you a safety net if usage is close to the limit.
