Are there any differences in calling rates between landlines and mobiles here?

Yes, there are typically differences in calling rates between landlines and mobiles in most places. Generally, calls made to landlines tend to be less expensive than those made to mobile phones. This can vary depending on the service provider and the specific calling plan you choose. Many telecom companies offer bundled packages that include unlimited calls to landlines, while mobile calls may incur higher charges, especially if you're calling across networks or to international destinations.

Additionally, it's worth noting that some providers may have specific promotions or discounts that can affect calling rates. For instance, if you are using a mobile phone, you might find that calling within the same network is cheaper than calling another network. It's also common to find higher charges for calls made during peak hours compared to off-peak times. If you plan to make a lot of calls, especially international ones, checking with your provider for the best rates or considering a local SIM card can be a wise choice. This way, you can avoid unexpected charges and stay connected without breaking the bank.
