The difference between 4G, 4G+ and 5G SA
When it comes to mobile networks, terms like 4G, 4G+ and 5G SA are often used as if they simply meant “more or less speed.” In reality, they describe different technologies, with concrete effects on browsing, video calls, hotspot use and connection stability, especially while traveling.
4G, also known as LTE, is the standard that made video streaming on the go and fast browsing common compared with 3G. It offers good performance for everyday use: maps, social media, email, app calls and high-definition video. Real-world quality, however, depends on coverage, network congestion and the frequency bands used by the operator.

4G+ is an evolution of 4G. It usually refers to Carrier Aggregation, meaning the ability to combine multiple frequency bands to increase speed and network capacity. In practice, if the device is compatible and the network supports it, 4G+ can provide faster downloads and a more stable connection in busy areas. It is not a completely new network: it is an improved 4G.
5G SA, on the other hand, stands for 5G Standalone. Here the difference is more structural: it does not rely on the 4G network “core,” but uses a dedicated 5G core network. This makes it possible to take better advantage of some 5G benefits, not only in terms of peak speed, but also lower latency, faster response times and more efficient handling of many connected devices at once.

- 4G: standard LTE network, suitable for most everyday uses - 4G+: an evolved version of 4G, with more speed and capacity thanks to band aggregation - 5G SA: true standalone 5G, with a dedicated architecture and more complete benefits
For users, this translates into practical differences:
- browsing and streaming: good on 4G, better on 4G+ - crowded areas: 4G+ often holds up better than basic 4G - cloud gaming, advanced hotspot use, real-time applications: 5G SA can offer lower response times - coverage: 4G remains the most widely available network in many cases
When choosing a travel eSIM, it is worth checking not only whether “5G” is listed, but also phone compatibility, the destination country and the actual support of the local network. With SIMAMMA, this helps you select the most suitable plan based on your destination and intended use, avoiding unrealistic expectations about the network available.
