Telefónica o2 Business Mobile Plan Comparison

O2 (Telefónica Germany) offers several main B2B lines: O2 Business Mobile S/M/L/XL for individual users with tiered inclusive volume, O2 Business Mobile Unlimited with unlimited data volume, and O2 Business Pool for shared data volume across multiple SIM cards. In addition, there are specialised tariffs for Connected Things (IoT), multi-SIM options, integrated Office 365 packages and O2 Business Premium conditions. List prices are rarely optimal: through the SAVECALL procurement pool, you secure conditions 20 to 40 percent below standard tariffs.

O2 operates the third German mobile network and has invested heavily in network expansion in recent years. In major cities and metropolitan areas, network quality is usually equivalent to Telekom and Vodafone, sometimes with higher download speeds. According to the Federal Network Agency, 5G coverage reaches over 80 percent of the population. In rural regions, coverage varies, where Telekom or Vodafone may have advantages. SAVECALL checks network quality site-by-site using Federal Network Agency data and O2 coverage maps for your main sites and travel regions

Pool tariffs bundle data volume of all employees into a shared pool, instead of allocating fixed volumes per SIM card. Heavy users can draw from the volume of other employees without anyone hitting throttling limits. This reduces total costs typically by 15 to 30 percent compared to individual tariffs. O2 offers flexible pool sizes from 20 GB to several terabytes, with or without EU roaming pool. Ideal for companies with mixed usage profiles of office staff and field service teams.

EU roaming is free across all O2 business tariffs according to EU regulation (Roam-Like-At-Home). Outside the EU there are three models: World Travel daily flat rates for data, roaming packages for weeks or months, and volume-based pay-per-use tariffs. For companies with frequent travel to the US, UK, Switzerland or Asia, roaming flat rates often pay off. O2 benefits from the global Telefónica presence for attractive roaming conditions in Latin America and Spain. SAVECALL calculates the economically best model based on your actual travel profiles.

Standard business tariffs at O2 range from 15 to 45 euros per employee monthly (list price), depending on inclusive volume, making them often the most price-competitive of the three network operators. Pool models significantly reduce average cost per user, often to 12 to 28 euros depending on pool size and usage profile. Hardware subsidies for company phones change the overall calculation. Through the SAVECALL procurement pool, you secure conditions 20 to 40 percent below list price. Concrete pricing in the initial conversation based on your current O2 invoice.

O2 makes particular sense for companies with headquarters in major cities and metropolitan areas, high data consumption at competitive conditions, lower need for coverage in rural regions and focus on cost efficiency. For companies with broad field service in rural regions or critical reachability, Deutsche Telekom (D1) often remains the first choice. Vodafone sits in the middle. For most companies a mix makes sense, for example O2 for office staff and Telekom for field service. SAVECALL analyses network quality of all carriers site-by-site.
