When I first arrived in Madrid, dealing with the phone system really puzzled me for quite a while. Spain’s telephone system differs somewhat from other countries, so today I’ll share the experience I’ve gained over these years.
Basic Format of Madrid Phone Numbers
All Spanish phone numbers consist of 9 digits. Madrid landlines typically start with 91, following a format like 91-XXX-XXXX. Mobile numbers begin with 6 or 7, such as 6XX-XXX-XXX or 7XX-XXX-XXX. If you need a Madrid phone card and are calling Madrid from abroad, dial Spain’s international code +34 first, then directly add the 9-digit number without adding 0.

Major Operator Comparison
Madrid has several main telecom operators. I’ve compiled a simple comparison table:
| Operator | Monthly Fee | Network Coverage | Features |
| Movistar | 25-40 EUR | Best | Established operator, stable signal |
| Vodafone | 20-35 EUR | Very Good | Convenient international roaming |
| Orange | 15-30 EUR | Good | Great value for money |
| Yoigo | 10-25 EUR | Average | Cheap but weak signal outside city center |
From my experience, if you frequently travel to suburbs or smaller towns, Movistar is the safest choice. However, if you mainly stay in the city center, Orange offers excellent value - that’s what I’m currently using.
Essential Service Numbers
I recommend saving these numbers in your phone - they’re very useful in critical moments:
Emergency: 112
National Police: 091
Municipal Police: 092
Medical Emergency: 061
Fire Department: 080
There used to be a 114 directory service but now everyone basically uses Google Maps. However, you should still remember Movistar’s customer service number 1004 and Orange’s 1414 - you can contact them directly with any issues.
Tips for International Calling
If you’re in Madrid city center and need to call home or other countries, the most economical method is using internet calling services like WhatsApp or Skype. However, sometimes you genuinely need to make traditional phone calls, which follows this format: 00 + country code + area code + phone number. For example, calling China would be: 00-86-10-XXXX-XXXX.
Quick reminder: Many plans don’t include international calls, so it’s best to confirm rates before dialing, or your bill might surprise you. I’ve spent quite a bit extra on this before.
Practical Advice for Getting a Phone Card
If you’re considering [Madrid enrollment consultation] and have just arrived in Madrid, I suggest starting with a prepaid SIM card. You can purchase them at major operator stores or large supermarkets like FNAC and Carrefour, typically costing 10-20 EUR. After using it for a while and understanding your needs, you can choose a suitable monthly plan.
Getting a formal plan requires an NIE or residence permit, plus a Spanish bank account. However, many operators now offer simplified plans for foreigners - you can inquire directly at their stores. Personally, I find that Orange and Vodafone staff speak decent English, making communication quite convenient.
One final note: mobile signal in Madrid’s metro is often poor - this is a common issue with all operators, not your phone’s problem. You’ll get used to it. Hope this information helps everyone!
