Frequently Asked Questions
Straight answers about MOQ, payment, sourcing, assembly and shipping — the same answers our sales team gives every day.
Ordering & payment
Before you order
Do you have a minimum order quantity?
MOQ is discussed per project. Sample and prototyping quantities work alongside production batches — tell us your target volume.
Which payment methods do you accept?
Bank Transfer, T/T and Western Union are all acceptable.
How fast is a quote?
Within one business day for most project briefs. A module or antenna recommendation plus a reliable estimate usually arrives quickly — we will tell you upfront if it is a larger BOM.
Products & selection
What we supply
Which brands of modules do you supply?
We work with established manufacturers including u-blox, Quectel, SIMCom, Telit, Sierra and Fibocom, and supply modules, antennas and USB dongles for M2M and IoT projects.
How do I choose the right module?
Send us the device function, target band, power budget and form factor. We narrow the options and recommend a fit — engineering support, not just a sales desk.
Do you make custom antennas?
No. We supply standard antennas matched to module bands and form factors, plus module selection support. Custom antenna design is outside our scope.
PCBA & quality
Assembly questions
Do you provide PCBA prototyping?
Yes. Module selection, PCBA prototyping, test and small-to-mid production are part of the service, run with our partner factory.
How are assembled boards tested?
Batches go through functional testing and quality checks with records kept per batch.
What documents ship with the order?
Original manufacturer documentation for modules and antennas, plus packing list and batch references. Certificates follow the module brand.
Shipping & support
After you order
Where do you ship from?
From Changsha with established routes to electronics manufacturers in 100+ countries.
Who will I talk to?
A technical contact who follows the order end to end — not a queue.
Still have a question?
Send it directly — a person answers, not a bot.
