I Face MobiMatter eSIM Network Failure In Moscow Despite Successful Activation

On June 8, 2026, I purchased a 10 GB eSIM through MobiMatter to use in Moscow. I had previously purchased eSIMs from the same company for use in other countries and had used them without any problems, so I chose MobiMatter again.

I successfully activated the eSIM before my trip, but when I arrived in Moscow, I could not connect to any network and was completely unable to use the line. Despite this, the system showed that only 0.05 GB of the package had been used, while the remaining 9.95 GB was still available.

Because of this problem, I contacted MobiMatter support and followed every troubleshooting step they provided. However, the eSIM still did not connect, the network issue was not resolved, and I was effectively unable to use the data package I had purchased.

I request a refund for the MobiMatter eSIM that I could not use. Alternatively, I would accept having the unused data allowance reissued and activated properly so that I can use it during my upcoming trip to Europe on August 29.

I expect MobiMatter to review this issue and provide a fair solution for the service I paid for but was unable to use.
