The case: Brazil eSIM stuck on roaming

The customer had correctly installed the eSIM "eSIM for Brazil Unlimited 10 Days (BR)", but found himself in a frustrating situation: the connection showed the roaming 'R' indicator but no data was working. He had already tried to configure the APN manually, but without success.

⚠️ The issue reported by the customer

«eSIM connected but no data (stuck on roaming 'R'). APN set to cmhk/global. Tried multiple networks. Please activate or reprovision.»

Message sent approximately 30 minutes after receiving the activation confirmation.

Dear M** C****** B******, thank you for the update.

We have received your technical report regarding the 'R' roaming status and the APN settings. We are immediately opening a ticket with our technical department.

Could you please send us a screenshot of your 'Cellular/Mobile Data' settings and the current APN configuration? This will help our technicians identify the issue.

Done. Still not working.
15:41
This is very strange. Can you tell us the smartphone brand and model?
Have you tried all three options?
Is the eSIM set as the primary data SIM?

In some cases, if everything is set up correctly, all you have to do is turn the phone off and on again.

📸 Technical screenshots shared during support

The customer sent us screenshots of his device (Samsung Galaxy S22 Ultra) to help us diagnose the issue. Below are the screens illustrating the correct final configuration:

Note: All screenshots were shared by the customer with consent for use in support purposes. Personal data and phone numbers were redacted prior to publication.


What happened and how we resolved it

The problem was an incorrect APN on the device. The CMLink eSIM supports three valid configurations, and it was simply a matter of selecting the right one. Once we verified the SIM Manager configuration and confirmed that the eSIM was set as the primary data SIM, a simple phone restart completed the process.

APN diagnosis

Configuration check

We ask for the phone model (Samsung S22 Ultra) and verify that the eSIM was set as the primary data SIM.

5

Restart and resolution

After restarting the device, the data connection works perfectly. Issue resolved in 4 hours.

🎉

«It's working now, thank you!»

The customer confirmed that everything works perfectly — less than 4 hours after the first report, with no reprovisioning and no need for complex technical interventions.


The technical proof: the data speaks for itself

We don't just rely on the customer's word — we also have technical confirmation. From our management panel we can verify in real time the data usage of every eSIM. Below you can see the CDR (Call Detail Records) logs of the customer's SIM: dozens of active data sessions in Brazil, all via the Vivo S.A./Telemig operator, in the days following the resolution of the issue.

📊 What these logs show

  • The eSIM connected regularly to the Vivo S.A./Telemig network in Brazil
  • Data sessions are continuous on 22, 23, 24 and 25 April 2026
  • Data traffic ranges from a few KB to over 100 MB per session — real and active usage
  • No abnormal interruptions after the resolution: the connection was stable

🔒 Privacy note

The technical panel screenshots have been anonymised before publication: the SIM card ICCID and the licence number have been redacted to protect the customer's privacy. Traffic data (dates, MB, operator) contains no personally identifiable information.
