To benefit from 5G speeds, you’ll need a 5G-ready phone and will need to be in a 5G coverage area. If you aren’t able to access 5G where you are, you’ll still be able to access older forms of coverage like 3G and 4G on your phone.

5G SIM Cards: By Network
In the following section, we’ll look at the 5G SIM-only deals on each mobile network in more detail.

1pMobile
On 1pMobile, you can Pay As You Go at the rates of 1p/minute, 1p/text and 1p/MB. There are no regular monthly charges for keeping your SIM card active but you’ll need to top-up your SIM card with at least £10 of credit every 120 days. If you’re a heavy data user, you can buy a 30-day boost. For instance, you can get 4GB data for £6, 10GB data for £10 or 50GB data for £15. For heavy users, this will be a lot cheaper than paying the 1p/MB rate (equivalent to £10 per GB).

Benefits of 5G
There are three main benefits to using a 5G mobile network:
- 5G has greater network capacity. 5G mobile networks have much more capacity for carrying mobile data traffic than older 3G and 4G networks. This means a lot more people can be using their device before the mobile network gets congested in an area. This can be important in many urban locations such as sports stadiums, train stations and shopping centres where lots of people will be using their phone at the same time.
- 5G has lower latency. Latency refers to the amount of time it takes for data to travel from your phone to the internet and back. On present-day 4G mobile networks, average latency is around 50ms (0.05 seconds). On 5G networks, this should drop to less than 10ms (0.01 seconds). This lower latency is important for online gaming, as well as new technologies like augmented reality.
- 5G offers faster download speeds. On 5G, it’s possible to get download speeds of around 150-200Mbps on average. This compares to around 30Mbps for present-day 4G mobile networks. Peak download speeds on 5G can be even faster than this (sometimes up to 1,000Mbps or 1Gbps). However, it’s unlikely you’ll be able to access these speeds very often to begin with.
See our guide to mobile network download speeds for further information.

| Can I get unlimited data on a 5G SIM card? | Yes. Most mobile networks now offer unlimited data plans with 5G. Prices currently start from £15/month for unlimited data on 5G. |
| What are the benefits of 5G coverage? | 5G coverage offers greater network capacity so download speeds are less likely to slow down in busy or congested areas. It also offers lower latency (~10ms) and faster download speeds (around 150-200Mbps on today’s 5G networks). |

I have now experimented with Vodafone Sims, and Yes, they work OK in Huaweis 5G router.
Even that I haven’t (on purpose) told them I am using their Sims on router instead of a phone.
Changed my Vodafone one recently to Voxi, as it was complicated to get a shorter contract with Vodafone. Works flawlessly on 5G and on unlimited tariff, 35£/month.
And not tied to a long contract !

How much is 5G Router ? Will Three 5G (unlimited data,minutes,texts) sim will work with any unlocked 5G router ?
Any suggestions
Ken replied:
Hi Kashif,
Thanks for your comment. You can buy a 5G router from somewhere like Amazon, such as the Huawei 5G CPE Pro 2 (approx £400). And yes, you can use the unlimited data SIM card from Three inside that device 🙂
Hope this helps,
Ken

If I have a sim only with mobile data, but turn on my wifi at home/work, do I need to turn off my mobile data in settings?
Ken replied:
Hi Pauline,
Thanks for your comment. There’s no need to turn off mobile data – your phone will prioritise the wi-fi signal if one is available.
Hope this helps,
Ken
