What is the best tariff?
Tariffs that can be canceled on a monthly basis offer more flexibility than fixed-term contracts. However, term contracts are often more attractive when offered. One of the best contracts was from Freenet (formerly) in November 2021 and May 2022 Mobilcom DebitelHere you can secure 50 GB with LTE in the Vodafone or Telecom network for 15 euros per month; Flat rates for telephony and SMS are also included. If you can, you should switch to a monthly terminable contract and then sign up for Black Week 2024.
Which network is good?
Depending on where you live in Germany, the network can vary greatly. For example, in Munich O2 Excellent in the city center area, but not usable near the metro and beach side. VODAFONE Provides high coverage throughout Germany; just like the network telecommunicationIf you really want to make sure whether the network is good at your desired location, you can always find the network coverage map from the respective provider. You should also ask friends and family for advice about whether they have good reception on the desired network.
The same basically applies to the new 1&1-network. Company brands such as winsim.de, sim24.de & Co. Advertise at extremely low prices for new customers. We have received some letters to the editor and the network appears to be devastated. If you have minimal reception on the 1&1 network, stay there. The network switches to Vodafone only if there is no reception. We are currently testing it and will decide around November or December 2024 whether we can even recommend the network.
What is the difference between monthly billing and every four weeks?
Some tariffs are billed not by calendar month, but every four weeks. Billing is done every 28 days, which is slightly more expensive in practice. You pay approximately 13 instead of 12 contributions per year, with billing every four weeks.
No reception, now what?
We’ve had it with O2, with Vodafone and with Telecom – suddenly there’s no network. Providers are often hesitant and you get nowhere. Here are some tips we’ve collected over the years:
- SEPA mandate LeaveEvery invoice should come by post – sometimes this works wonders if service is not provided.
- screenshot From each speed test: Consumer Advice Center There are very clear guidelines that can help
- Don’t be left behind: providers are obligedTo fulfill the contract on their behalf
