Questions about ordering
How do I get a price?
Ask for a written quotation. Use Request pricing on any product page, WhatsApp +968 9664 1360 or email info@touchscreens.ae with the model or part number, the quantity, the delivery location in Oman and whether installation is needed. The quotation covers pricing, availability, warranty and installation options.
Do you deliver across Oman, and how long does it take?
Yes — to Muscat, Salalah, Sohar, Nizwa and the other governorates. Lead time depends on the model, quantity and configuration, so it is confirmed in writing on the quotation and again when your purchase order is acknowledged.
Do you install?
Yes. Installation is available across Oman through our partner installation teams. Its scope — mounting, cabling, positioning, commissioning and handover — is written into the quotation, so anything outside it is clear before the visit.
What warranty applies?
The manufacturer's warranty applies, with the terms confirmed on your quotation. The quotation states the warranty holder, period and service level, and we coordinate any claim with the manufacturer or its authorised service partner on your behalf.
Do you support government tenders?
Yes. We quote tender quantities and supply what a tender file needs: an itemised quotation addressed to your entity, manufacturer datasheets, technical compliance sheets, the delivery and installation scope, and a warranty statement.
Can I get the quotation in Arabic?
Yes — in Arabic, English or both. Manufacturer datasheets are usually published in English.
