The World Text SIM Hosting service uses a customer supplied SIM card (not to be confused with Virtual SIM Hosting) and is especially of use for developing countries. Multi-redundant IP connectivity and power back-up, ensuring the World Text SIM Hosting service is market leading.
Using a SIM card provided by you (we recommend a contract SIM), once received this is securely setup on our SIM hosting hardware, which has multi-redundancy built in. Text messages received are automatically and immediately returned to you.
Hardware based SIM hosting is reliant on three things; IP connectivity, power and local cell tower signal. While we can't influence the latter, we have both backup IP connectivity and power.
Yes, we recommend a contract SIM card. Pre-pay SIMs can be used, but full international roaming is required, and clients must ensure the SIM card remains 'in-credit' and any other operator terms are met to ensure the SIM remains active.
Yes (sort of). Whilst you can't directly receive inbound calls over SIP, you can setup 'call forwarding' - this setup and any costs incurred would be between you and your network, and should be configured before sending your SIM card to us.
You can send SMS to most countries using the SIM card number as your source address (sender ID); this is what is shown when the message arrives on a handset, which will enable replies.
The SIM itself is not used for sending SMS, so you would send using the World Text platform via any of our interfaces (which include HTTP REST, SMPP, Email to SMS or Communicator Pro web SMS software) just paying for the messages you send.
When any inbound messages are received by your SIM, the World Text SIM hardware and SMSC will pass these to you without delay by your chosen method. Our unique Auto Responder will pass messages to you by email for low volume or HTTP for high volume.
SMPP is also available.
