- Check the portal to determine if the data in Reach Central is throttled or paused
- NO: check if data is used; if additional data was added, ask customer to restart their device
- YES: if there was no upgrade or added data, ask customer if they'd like to do so
- If they do not, advise the customer their data will reset on the next cycle date
- YES: there is no reason for a pause or throttle - contact tech to remove throttle / pause
- Create a ticket to sync the portal to the network side
- Contact customer when this is completed
- Find the IMEI in Reach Central under Manage Lines (be sure to click on the line in question)
- Find the IMEI on the phone in question
- iPhone: Go to Settings > Tap General > Tap About > Look for the serial number
- You might need to scroll down to find the IMEI/MEID, and ICCID
- Android: Go to the Settings app > Scroll down and select About Phone > Scroll down to find your IMEI number

- On the Mobile Tab in BOLT, click on Reach Central and perform a network reset
- If customer is calling on the mobile phone having issues, let them know the call will disconnect
- Confirm the callback number and tell them to turn the phone off and on after the call disconnects
- **Call the customer back to continue troubleshooting**
- Ask the customer to make sure the software version on their phone is up to date
- Check with customer to make sure data is turned on (on phone, specifically in their settings)
- Check if there is a data pause turned on (if customer requested their data be paused)
- Is it a particular app or browser having the issue; can they use others or are all data service not working
- Check for Mobile Signal
- Turn off WiFi and check for LTE, 4G, or other types of symbols
- If there is at least one bar of 4G/LTE, ask customer to access the internet, send an SMS, and make a phone call
- Physical SIM: try a spare, compatible phone with the SIM; if SMS, talk, and data still don't work, most likely requires a new SIM
- Ask for the physical address where issue is being experienced the most, if available
- This helps determine possible outages at service address
