Frequently Asked Questions

Can I use this SIM in a router?

No, the SIM will not work in a router as it is designed to work in your Smartphone / Mobile phone to optimize the speed and quality of the connection.  If you are looking for a service that will work in a router, kindly visit: https://openweb.co.za/uncappedlte

What is the FUP for Telkom One Business's Unlimited Telkom Minutes?

Generally, there is no limit, however, if we detect that a user is using large quantities of these minutes that do not fall in line with the average percentile of users, we will contact the user to rectify the issue.  If the abuse continues, we reserve the right to terminate the service.

What are Telkom to Telkom Calling Minutes?

These minutes will allow you to call any Telkom Fixed Line or Mobile phone on the Telkom network using its own minute bundle, so it will not take minutes from your All Network Calling bundle.

Am I Guaranteed to be on the Telkom Network?

Yes, our Telkom One Deals offer you pure Premium Telkom Mobile access with no location locks and it roams on Vodacom and MTN when you are outside of a Telkom coverage area.

What happens when I move? Can I use my Mobile service at another location?

The great thing about the Mobile Data Wifi SIM is that you can literally use it anywhere in South Africa where there is coverage. It is a truly mobile service.

What speed will I get on the Mobile Data SIM?

Speed is reliant on your coverage and which router or phone (device) you use. If your coverage is great, you will get great speeds. On Average users on 4G get between around 10Mbps and 50Mbps speeds.  If you have a 5G router or phone and are within an 5G coverage zone, you can get theoretical speeds of up to 200Mbps!

I have used up my data, can I topup?

Yes you can.  Kindly visit: https://topup.openweb.co.za

What our clients have to say

I have been using their R399 Smartphone package now for over a year and can safely report that it does exactly what it says on the box.  The calls are HD quality and the data works flawlessly.  It is a little slow once I hit the FUP, but it still worked.  They never disconnect your data completely.  I went over to https://topup.openweb.co.za and bought an FUP lift token when I needed the full speed and that worked really well.  Overall, great value for money

Top Service and Delivery – Big Thumbs Up. Try these guys out, really went above and beyond to get my parcel to me on time even though I live in an area that couriers do not like to go to most of the time. I felt like I was informed all the way and feedback time usually pretty quick. By far one of the best tech companies I dealt with in South Africa.

I have been using OpenWeb for the last 8 years. I have my 14 x branches across South Africa using a variety of ADSL & VDSL products from the company. I would just like to say thank you for being such a superb partner over the years. Oh and the gift you sent me for my birthday was such a surprise!

Guys, thank you so much for the help last week. Leon spent almost 3 hours on the phone with me trying to sort out my internet. Guess what, it was a fault on the router which we identified. I am so grateful for the wonderful service you provide. No company can match the level of care you have for your customers!

Hey OW, remember when I emailed you last week about the Fibre trucks installing Fibre in my area? Well, it turns out that the truck was for me! My new Fibre line is up and running and I am sitting here watching a download peak at 99.8Mbps! To say I am happy is an understatement of note! Best wishes, your customer for life, Rowan.
