Network Readiness

Quick Test: Checking Network Connectivity Across All Applicable Carriers

Follow these steps to ensure that your devices have network connectivity to the CTC server:

  1. Obtain SIM cards for all the airtime carrier services you are using.
  2. Gather ESNs of selected test devices and insert a SIM card in your devices.
  3. Verify that test devices are supported with the latest firmware provided by CalAmp.
  4. Send an email to [email protected] that includes the following details:

    CTC server region (United States or Europe).
    Destination account name and account ID.
    Subaccount, if applicable.
    Any groups that devices are nested under. (You must specify these in order for groups to be created.)
    All the ESNs to be migrated.

📘

NOTE

When CalAmp receives this email, a ticket will be created to migrate the list of ESNs to the CTC Admin account within 24-48 hours.

You will be notified when the test devices have successfully been moved over to CTC.

  1. Test each SIM card to verify that the devices are reporting to CTC Admin, referencing the last ID report.
  2. Perform firmware or script downloads on to your devices to ensure that your devices are functioning correctly.
  3. If you are using more than one carrier or various airtime plans at a single carrier, repeat steps 1-6 to test network connectivity across all your applicable carriers.

Determining Your Airtime Settings

Contact your carrier(s) to determine your airtime settings. If you are using more than one carrier or various airtime plans at a single carrier, you’ll need to obtain answers to the questions in our sample letter about each airtime and APN combination. For your convenience, we have drafted an airtime plan sample letter for you to send to your carrier(s):

AIRTIME PLAN SAMPLE LETTER

NOTE: Below is a sample email we want you to send to your carrier. We are not sure how many airtime plans and specific APNs you are using with each carrier. If there is obviously more than one airtime plan at the carrier, the below questions need to be asked about EACH airtime/APN combination you are buying from them.


Hello Carrier,

We have some questions about our airtime plan that we need help answering. If there are multiple airtime plans, we need answers to these questions for each airtime plan/APN combination.

We need to know if the APN we use under our airtime has access to the open internet. We are going to be changing the maintenance server we use for our product to a different IP address and want to ensure that there will be no complications. If we do use a private APN that does not have access to the open internet, we will need to “poke a hole” in our APN network to allow traffic to the specific new maintenance server IP address. Can you help us understand how our airtime plan is configured?

We also need to make sure that the airtime plans have access to a DNS server. This server will resolve the IP address of a URL. Our new maintenance server is an actual URL that must be resolved into a publicly accessible IP address. We need to ensure that our airtime plan has a DNS server included so that this resolution of the URL works properly. If it does not have a DNS server included, we need to make sure that one is set up correctly.

These are the details for the CTC maintenance server:

URL: dm.calamp.com
IP address: 18.205.15.12
Port number: 20500

Can you please help us with the above questions?

Thank you,

Determining Your APN Settings

You can determine your settings if you are using a public APN as follows:

  • Perform a DNS lookup of the URL.
  • If a DNS lookup is unavailable, contact your carrier for a solution.

If you are using a private APN, you must consider all of these aspects:

  • APN: Contact your carrier to make sure that the IP address is accessible from the private network.
  • VPN: If CalAmp was involved in the original VPN setup, reach out to our Migration Support team to work through a solution.
  • Proxy: If you are using a proxy server (previously forwarding data traffic to PULS), contact the team who originally built the proxy server to make changes that allow data to be sent to CTC.
  • DNS lookup: Perform a DNS lookup of the URL. If a DNS lookup is unavailable, contact your carrier for a solution.
