as I have a mobile subscription from a foreign country, every time I am in CH, I have the possibility to switch between carriers. By far, where i am located, Swisscom has the best coverage. Only issue is that 4G connectivity is heavily restricted, resulting in very low internet speed, not allowing web browsing or messaging.
Although, when switched to 3G / 2G, the Swisscom network seems to work.
Is there something that needs to be specified in the phone's settings in order to have a 4G with Swisscom that works ?
Hi there, Apparently there are configuration problems on your phone.
Every time you "change" the provider - that is to say change the SIM, you should receive a "welcome message" or a "setup message" from the provider.
Because you now have various configurations (e.g. from your home country e.g. Vodafone in Germany, Salt and Sunrise from your previous tests) available on your device, it is possible that the device cannot connect correctly to Swisscom.
I therefore always recommend that you insert a different SIM, even if it is within the country to remove the configurations.
Note that the APN settings are adjusted in the "Setup message".
You must therefore reset them and overwrite them with the new ones from Swisscom.
Hi, thanks for your reply. My issue is a bit different, apologies if it was not clear on my side: I do not have a subscription with Swisscom. I have an "European" subscription from Vodafone which includes Switzerland and have the possibility to select carriers (Salt, Sunrise & Swisscom) when in CH.
Nevertheless, every time I switch to Swisscom 4G's network, it seems to be limited, and I'm not able to even load a web page. Swisscom 3G works fine, but it's 3G.... other carriers do not have a better coverage in my location.
Is there any known limitation in Swisscom's 4G network when used with a foreign provider ?
In fact it is the case that Swisscom limits the speeds to 3G and 4G to the contract - I think in your case a contract with similar services is taken as a comparison.
With us it is the case that very small subscriptions usually have 30 Mbit / s. Medium subscriptions get 50 Mbit / s and the large subscriptions then have a maximum of about 100 Mbit / s.
You can only have faster internet if you pay for something.
However, I do not know exactly what the contracts between Vodafone and Swisscom for this offer are. I would suggest that if you are in Switzerland, just go to a Swisscom shop and ask. Alternatively you can call: 0041 800 800.
If you are in the country where your subscription is connected, I would ask Vodafone directly. Most of these can also help you.
But I'm still guessing a configuration error on the part of Swisscom or with the APN access on your phone.
I personally have tried different SIM cards, among others from Sri Lanka and Great Britain, but the speed was not slow but about the same level as in the other countries (Sri Lanka: 50 Mbit / s; Great Britain: 30 Mbit / s ).
