I need a bulk order of RJ11 to RJ45 adapters quickly. Should I choose Amazon Prime or Ships from RetailAndBulk?

Ships from RetailAndBulk is fastest for bulk orders. We ship all RJ11 to RJ45 adapters in one shipment the next business day from our NY workshop where we make them. Prime may need to transfer stock to one warehouse first or send multiple packages.

Are these RJ11 to RJ45 adapters compatible with all landline phones such as AT&T, Panasonic, and cordless phones?

You can use any landline or cordless phone just like you would with a regular phone cord. This adapter simply lets you use an Ethernet cable or your home’s Ethernet wall wiring for phone connections.

Does this Ethernet to phone line adapter support broadband data connection?

No. This adapter does not carry broadband or network data. It is designed only for landline or VoIP telephone connections.

Can I ask about a specific use case for this adapter?

Yes, RetailAndBulk support is available for any questions you may have.

Do you offer bulk discounts on large orders?

Yes, if you have an Amazon Business account, you will see it when adding large quantity to cart. We’ve served many large-scale projects, including hotels, retail chains, new constructions, schools, hospitals, TV stations, and fire departments.

Worked great

Worked great. And I like the fact it is a short piece of cable with a coupler, not just a cable with a male end and a female end

Good item, but not compatible with the service

The item seems to be well made and it is very easy to connect. I had to return it only because it wasn't compatible with my modem and routers.
