Response time was super fast. Whenever I had questions navigating mobile connectivity in Japan, the support team patiently helped me until everything was settled.
“Extremely satisfied with the service. Will definitely recommend to friends needing a SIM!”
Clear registration steps and very polite staff. I feel 100% confident recommending C.T.S to students and co-workers moving to Japan.
“Setup was smooth and ready in minutes. Strong network coverage and great service.”
Followed the simple step-by-step guide and internet was working right away. Rock-solid connection on the nationwide SoftBank network.
“5 stars isn't enough, I'd give 10 out of 5 stars for the extraordinary help!”
When I had a mix-up with the delivery locker at my building, support immediately contacted the courier service to ensure my package arrived safely.
“Pre-order guidance was super helpful and warm. A reassuring 5-star experience.”
They explained the data allowance plans and group bundle discounts clearly so I could make the best choice without hesitation.
