GeoSIM Most Asked Questions (+4477)
Where Does GeoSIM Work?
GeoSIM works in over 200 countries and more than 550 networks, many of which, receiving calls is free. Check our coverage and call calculator to see how little you pay.
What Do Calls Cost?
Call costs vary. Check our interactive rate calculator for voice calls and SMS/Texts.
What Does Sending A Text Cost?
Text costs vary depending on your location. Check our rate calculator here.
Will It Work With My Phone?
Yes, GeoSIM works in 99.9% of GSM handsets. If you do not have an unlocked handset, we can supply one.
What Network Do You Use?
GeoSIM uses the existing GSM networks, such as Vodafone, Orange, T-Mobile, O2, ATT, Telefonica, SFR, MTN, Digicell and many other GSM networks around the world. It will automatically select the strongest signal and lock on to it. You may find that as you move around, the network to which GeoSIM uses changes. Regardless of which network you are on in a particular country, the charges will be the same. This means you actually have a better service than the locals!
GeoSIM will operate on the following GSM Bands/Frequencies:
Note: In some countries you will require a Tri-band or Quad band mobile phone.
In Japan and Korea you will need a 3G handset which has UMTS/WCDMA 2100 functionality. You should ensure you have a suitable handset for the region you are travelling to otherwise your GoeSIM (or any other SIM) will not function. This is a handset requirement and not a GeoSIM requirement.
U.S. Number Recycling. If you have a dual number GeoSIM with a US number, your US number will be valid for 60 days. If you do not use your SIM within the US at least every 60 days, then your US number will be cancelled and "recycled". This is a US regulator requirement and not a GeoSIM condition. If your US number is recycled simply dial *160# to obtain a new US number. Unfortunately the same US number cannot be reasigned to your SIM.
SMS - GSM vs CDMA
GeoSIM works using the GSM system which is adopted in the vast majority of countries around the world by the vast majority of major networks. In some countries, the CDMA system is used by some networks. For example, some networks in the USA use the CDMA system.
SMS between GSM and CDMA networks is not always possible, although some networks may be able to translate between GSM and CDMA. Any failure of SMS delivery or receipt between a GSM network and a CDMA handset is not the fault of GeoSIM, but a symptom of two differing systems.
How Long Does My Unused Call Credit Last?
Your call credit will last at least 12 months from the time of purchase. See below regarding annual renewal fee.
Is There An Annual Renewal Fee?
Yes. A nominal annual fee of N5,000 is charged. This fee is charged to us by the telecom network service provider and unfortunately is one that we must pass on. It is not a charge levied by ourselves.
Unlike many Global SIM companies, we do not take unused call credit away from you if it is not used within a short period of time - some companies will take unused call credit from you after just 45 days.
One "Leading Brand" charges a daily usage charge of 39p and "Credit Holding Charge of £2 per month". This means that if you use your SIM, you are charged 39p per day (£142.35 per year!) and if you don't use it. £24 per year.
In line with our Clear Pricing Policy we do not hide this fee in higher call and call connection charges, or charge for non connected calls.
Our advice is to keep your SIM active by paying the N5,000 annual fee - it's very cost effective and means you won't lose any call credit.
Before the annual anniversary of your card, you will be contacted to see if you want to keep your GeoSIM active and keep your call credit. If you do, we will charge a N5,000 + VAT service access charge. This will keep your GeoSIM active and your call credit will roll over to the next year. If you decide not to keep your GeoSIM active your service will be permanently suspended by the carrier and any call credit cancelled.
How Do I Pay My Renewal Fee?
You will be contacted by about 6 weeks, 3 weeks, 1 week and on the due date, email reminding you to renew. The email will contain a link to the relevant page on our website so you can pay by by credit card or PayPal.
How Do I Add Call Credit?
You can add call credit 24/7 via this website by contacting us.
How Do I Check My Call Credit Balance?
Dial 187 from your handset. After each call you can opt to receive a free text detailing the cost of your last call and your remaining balance. Dial 188 to switch this feature on, and 189 to switch it off. You can also check your account balance online in your GeoSIM online back office/SIM Admin area. Once logged in got to "Billing" the "Account". Your live balance will then be shown.
Does GeoSIM Have Voicemail?
Yes. You can listen to your voice mail from your handset and online via your back office. Retrieving voice mail is FREE from your SIM admin area online and costs the same as a call back to the UK from whichever country you are in.
Can I Forward Calls From GeoSIM To Another Phone?
Yes. You can forward calls to your GeoSIM onward to any number in the world. For fowarding costs visit Call costs and Coverage
Can I Transfer My Existing Number To GeoSIM?
No. "Porting" of your existing number to GeoSIM is not currently possible, nor is porting your GeoSIM number to another provider. PAC numbers are not available for GeoSIM numbers.
What Does It Cost People To Call Me?
GeoSIM 0770 numbers are main land UK mobile numbers.
Calls to these numbers from a BT (British telecom) landline cost about 17p per minute during the day, 13p during the evenings and night and 8p at weekends.
The GeoSIM number range is also eligible for BT Friends & Family discounts which reduce the above prices by 10%.
O2 allow calls to GeoSIM from your monthly bundle or allowance. Other networks may charge their "standard Rate" which is normally between 10 and 40p per minute. Please check with your service provider. We have no idea why some networks charge to call another UK mobile, but its probably for the same reason they charge high roaming charges!
Please note that we try to keep up to date with other carriers tariffs, but they may change their pricing to call various number ranges, including GeoSIM numbers before we can update our web pages.
If you are a non UK customer, your network or carrier will probably charge you for calling a UK mobile. You need to ask your carrier or network what they will charge to make an international call to a UK mobile.
Does GeoSIM Support Data?
Yes! For rates and coverage check here
Is Caller ID Supported?
Yes, Caller ID is supported on GeoSIM.
Caller ID does depend on any intermidiary carrier passing it through their system, provided they do, GeoSIM will present the caller ID on inbound and outbound calls.
