Dear Valued Customers:

In observance of International Labor Day, UTSTESTER will be closed from May 1 to May 5, 2026, for a total of 5 days. We will resume normal operations on Wednesday, May 6, 2026.

1.  During the holiday period, our business department will remain available for online product inquiries. However, order processing and shipping will resume after the holiday. We kindly ask all our clients to plan accordingly when submitting orders and coordinating communications.

3.  If you have urgent business needs during the holiday, please contact our emergency contact person. We will respond promptly to the best of our ability. For non-urgent matters, please resume normal communication after we return to work.

We sincerely apologize for any inconvenience caused by our holiday schedule. We thank you for your continued trust and strong support of UTSTESTER. We deeply value our partnership with you and look forward to continuing to provide you with high-quality products and professional services after the holiday.

We wish you and your team a Happy International Labor Day! We hope you have a pleasant holiday, stay healthy, enjoy smooth work, and experience thriving business!
