Thank you for sharing your experience with us. We strive to provide excellent service and support to all our customers, and we take your feedback seriously.
Upon reviewing your case, we found that the initial plan selected that you purchased did not include Panama in its coverage. We promptly addressed this by switching your plan at no additional cost. Additionally, we provided detailed instructions on how to properly install and set up the eSIM.
When you reported the issue, we requested a screenshot of your settings to better assist you in resolving the matter. Unfortunately, we did not receive the requested information or a follow-up email as advised.
We are here to help and want to ensure that you have a positive experience with our service. Please feel free to reach out to our support team at your earliest convenience so we can assist you further.
Thank you for your understanding.
